Magic Lantern Forum

With help from members, I have compiled a list of card speeds with Magic Lantern.  Feel free to add more results, details at the bottom of this post.

The results for all cards and cameras tested, can be found here:
https://drive.google.com/drive/folders/1yh9doUXKpvkOfI8kpiOaLCHnwuI_hBfr?usp=sharing

Posted results in this thread that haven't followed the requested testing procedure have not been included in my dropbox link, testing in playback mode etc.  Please follow the instructions below if you would like your results included.

Some notes!

The fastest CF card results I have, show the KomputerBay 64GB 1000x @ 93MB/s.
(https://s15.postimg.cc/3zaj5z22j/Komputerbay_64_GB_1000x_CF_5_D3_24p.gif)

However, all KomputerBay cards tested above 85MB/s on the 5D3, and the Lexar 64GB card I have results for, also benchmarked above 85MB/s.

Based on the results of one card, the 5D2 appears to be around 15MB/s slower then the 5D3.

Higher frame rate modes in Canon settings, results in slower speeds.  That is to say, 24p modes are fastest, and 60p modes are slowest.

Crop mode in Magic Lantern raw recording, switches to 30p mode.

Cameras have hardware limits to card speeds, it doesn't matter how fast the actual card is.  These speeds (and other useful information) can be found here:  https://docs.google.com/spreadsheet/ccc?key=0AgQ2MOkAZTFHdFFIcFp1d0R5TzVPTVJXOEVyUndteGc#gid=5

---

To perform the benchmark, select the benchmark option in the debug menu, then choose the Card R/W benchmark option.

When the benchmark is complete, a PPM file (BENCH0.PPM) will be on the card that has ML installed, and you can use the free image viewer Irfanview (http://www.irfanview.com/) to save the PPM as PNG.
Upload the files to a free image host (https://www.google.com/search?q=image+host) and post the links here, preferably using the img tags.

Please include the camera used and card type +capacity, and test in movie mode with Global Draw OFF.

Does Canon menu FRAME RATE setting matter?

EDIT: Can anyone confirm my findings of Canon menu FRAME RATE setting making a difference?

UPDATE: Confirmed, higher Canon menu FRAME RATE setting slows down write speed :-\ :-[ :'( >:(

No idea.  I'll test that and Canon resolution modes when I get back home.

After I asked the question I grew a brain and realized I can do the test myself ;D

But some confirmation would be nice too...

Ha.

Updated OP.  Higher frame rate modes are defiantly slower.

Updated OP.  Higher frame rate modes are defiantly slower.

You know, I wouldn't have expected that. Thinking back though, it was suggested for the 650D that you set it to 1080p@24fps in canon menu (maybe other cameras too), but for the 5D2 and 5D3 I was using 1080p@30fps thinking the higher frame would/might put the camera into a faster 'mode'.

Well, I'm glad you started this thread, cause everyone is always asking 'which card should I get for my camera...' :D

Yeah, we have lots of useful threads, but it would be good if they were like general discussion about the cards, and the important bits, "how fast is this card", is compiled into one list.

I recall some people saying crop mode is slower, and this makes sense now, as crop mode switches to 30p.

Ok just wanted to add this info for 650D / 700D / probably 70D and 6D. Found some benches done in photo mode for taking RAWs in burst. Looks like the sandisk extreme Plus 80MB/s is best performer for these cams having crippled sd controller. Ofc results need to be compared in camera with ML. Maybe I will buy one and test some days later.

Can you re-upload please, because I can not expand your screenshots. PS: whats your opinion performance wise of Komputerbay 1066x 128gb for 5D mark III? I'm considering also.

I have these results for my 2 newest cards, right from the pack:

This one is the first card I've got in July last year, if you only do 'quick format', it is not able to do Full HD with my MKIII without dropping frames. With 'full format' in my PC, it sometimes skips (depends on the build) on a few takes, and after that can reach 1920x1152 without any problems:

(http://i1063.photobucket.com/albums/t506/Sganzerla/bench03_zps55743027.gif)


This one is worth for takes of around 5 seconds, as it skips after that. It is too slow for continuous Full HD:

I've never used the KB 128GB 1066x, but I hear they work very well. STAY AWAY FROM KB 128GB 1000x, even KB realizes how bad they are and are selling at a discount because of it.

Where/When can we setup the cluster size ? using computer or the Eos ?

On PC during card format (right click on it to bring up options). Mac IDK

Has to be done in Terminal for Mac afaik, with diskutil

Considering the Sandisk Extreme  ::) ::) ::) ::)

Limited by card interface to about 41 MByte/s. And in movie mode you won't even reach that one.
See a few posts above. Extreme Pro on 650D in movie mode doesn't hit the roof.

(it used to work fine but now it won't record longer than 1 second... see related post)

Got Lexar 1066x 128GB  - somewhat a disappointment.

In USB3/UDMA7 it showed stable 134 mb/s /write, but in playback on 5D3 (1.2.3) it was max 112mb/s, typically about 108. ~10mb/s slower than KB (117-119). Unlike KB card it never stalled in the beginning during recoding at 24fps, but couldn't sustain anything approaching 90mb/s (1:1 modes, 30fps, etc.).

I wonder if it is typical. Still waiting for my Lexar 64 GB 1066x  from Adorama. It seems like it's unrealistic to expect stable 90+ mb/s from 128GB cards?

For now, I'm guessing we'll need 1200x (180MBps theoretical read speed) card to eke out reliable 100MBps write???

I've got my Lexar 1066x 64GB. It's the fastest card I've tried, faster than SanDisk 160mb/s 128GB, I rented for my SD trip.

I consistently get 120.8-120.9 MB/S writing and 153.8MB/S (yes, exactly this number) reading. Faster than any of 128GB cards I tried before: 2xKB, 4xTranscend. My USB3 says it can do 138MB/s write. Reading is the same as in camera. Pretty fast.

It can do about 15 secs of 30fps at FullHD, more with card spanning (SanDisk Extreme  64GB), but can't sustain it (GD off).

How the heck people get 30fps? Or there is something I don't know? Like they don't get it at FullHD?

Are those speeds in-camera with 'movie' mode setting?

No, photo mode.
Movie, 24fps, GD OFF: 90W/120R.
Movie, 30fps, GD OFF: 85.5W/115R.
All on 1.2.3.

Don't get excited, the 5D3 SD slot is hardware limited to around 20MB/s.  Doesn't matter how fast the card actually is.

I've compiled the results so far into a dropbox folder, updated the OP and added some notes.  Feel free to let me know if I missed your results.

Thank you very much for telling me , otherwise I might buy one...
:P

Noobie alert!!

Apologies in advance but despite spending much time to the simple answers for myself, I now have to ask.....

Is it a case of just picking out the highest write speed you get from a 5 min bench test that determines the speed of a card? Also, what is the minimum card write speed for shooting RAW on a 5D Mk3?
What happens if your card is not fast enough - do you get footage in smaller dimensions or missing frames?

thanks

What usually happens is the recording will just quite, and the camera will prompt you with a message, "recording has stopped" something like that... At least on the T5i that's what happens..

sandisk extreme SD card, 45mb/s, dos not reaches this speed because 5D3`s limit is 20mb/s? Even with ML software installed?

so, what`s the 5D3 CF slot hardware speed limit?

thanx  ;)

Hi everyone,
first Post here. So i did some Benchmarks with 5d Mark III and some KomputerBay Cards 64 GB 1000x UMDA7. All purchased within the last week,

First Card:

[Edit]Update Post. Now with Benchmark in Movie Mode and GD Off. No Warmup.[Edit]

For own reference here a SanDisk Extreme Pro 90MB/s 16GB:
(http://filehosting.procypher.com/free/20141014/4_SandDisk-Extreme-Pro-90-MBs.jpg)

[Edit]I forgot to tell the SanDisk was just a 16 GB Card. As mentioned by Walter Schulz below, Global Draw was off on the SanDisk. The Test with the SanDisk was not really for reference. More a self check for me how the KomputerBay perform to a Brand Manufacturer. Nonetheless i thought GD On makes the card read/write slower, am i right?[Edit]

I use them all formatted as FAT. The KomputerBay Cards came pre-formatted as ExFAT. Reading speeds on the Mac were horrible so i formatted them within the Camera and they performed very good in Black Magic Speed Test and AJA System Test. Used a Transcend USB 3 Card Reader.

Recording seems to be continuous, tried some 1.5 to 2 minute takes. Also when splitting in 4GB chunks looks good.



best regards,
Heiko

It doesn't make that much sense to compare card benchmarks taken with Global Draw ON with another card's benchmark with GD OFF.

Hi Walter,

sorry for that. Played around with settings between the Benchmarks. Updated post with KomputerBay 64GB 1000x Movie Mode and GD Off.

Hi Why not try Renice S8 Series Compact Flash Card.

I have a Canon 5D Mark III and I just purchased a Lexar 128GB 1000x CF Card UDMA 7, formatted it to exFAT and after doing numerous benchmark tests, with GD on and off and in video/picture mode, I get the same low results of 29.9 MB/s write and 13.6 MB/s read. 

Those readings sound completely wrong.  I can only record video in ML for about 2 seconds before it skips frames and shuts off (shooting at 1080/23.97). 

Do I have a bad card?  Am I missing something?

Any help would be greatly appreciated.  Thank you!

I suppose you purchased a faked card. Contact dealer to get a refund or a replacement.

Obviously RAW/MLV write speeds are slightly over the edge in 1.1.3... my question is do you guys think I should keep this KB 128gb 1066x card?

**EDIT**

I'm starting to like it as each day goes by... the more I learn its 'sweet spot' for each settings... the more I enjoy the practical freedom of 128gb.

I've also noticed the 5D3 can push it to close 103-106mb* during 3x crop 2.5k which can be just absolutely marvelous! (*obviously only for 10-20+ seconds depending on settings)

I wonder if it can do more with a 1200x speed CF card?

Just wanted to share: I have reverted to 1.1.3 and was able to record FullHD @30fps (though, zero LV feedback), but what is more astounding - 2560*1090 @ 24fps, in crop mode. Over a minute! Needless to say, it looks better than anything natively FullHd. Keeping in mind that 1:1 sharpness in raw is better than sharpness of full frame raw... wow.

Recording was done to CF (64GB, 1066 Lexar) and SD (64GB, 95mb/s Sandisk), in parallel.

Samples, please!
Why? Because 5D3 uses binning, other cams (except 7D2) use line skipping in uncropped video recording.

AFIK 5D3 doesn't do line skipping (that's why it is superior in low-light, when compared to FF cameras with line skipping, but I suspect it still throws away information), it does binning. Thanks to this resulting FullHD bayer mosaic-ed image isn't as sharp as optimally resized.

Sorry, I am too lazy to repeat my charts shots :) It becomes immediately obvious, once you pull out full frame dng to ACR - sharpness is lower, but what is worse - the binning artifacts are raising their head if you try to sharpen the image - location of RGGB elements is different in each binned pixel. So you can't really make it SUPER nice at 1:1. Obviously, 1:1 has none of this - it is as pristine as normal photo raw. Though, micro-contrast of full frame is still superior, when compared to crop mode.

In fact, if you think about it - due to 3x3 binning over 2x2 bayer: 1) the best case is 5 green elements over 3x3 2) the worst case is 1 R/B over 3x3. So, if it is straight binning over 3x3, we still lose plenty of incoming light.

Naturally, the issue with crop mode is framing and focusing - crop window isn't aligned with the center of the center of sensor. Though, I think custom crop marks can be added via bmp (there are 5 of them available, but for different purposes).

There are currently three Kombuterbay 64GB cards available: 1000x, 1050x, 1066x. Which one should i get based on your experience?

1066x rocks my socks...

So is the 1066x the fastest? I thought the 1000x is the one to go..?

@DeafEyeJedi
does your KB 1066x 128gb allows for the 1080p 24/25p continously recording?

Confirmed for both 24/25p in 1080p.

Both RAW & MLV.

Flawlessly.

So far!

Sometimes in life it's worth to bite the bullet when timing persist.

Also due to mixed reviews, I'm afraid I've waited too long on ordering the KB 128gb 1066x since now it has given me so much flexibility in shooting RAW/MLV for long period of times in between takes without hesitating on swapping cards as often.

Saving up to get a bundle package one of these days!

I also use few Lexar Pro 32gb 1000x that runs great as well as few Sandisks Extreme Pro 32gb but w limited spaces obviously.

I'm a bit confused with the card speed hardware bottlenecks ::). I have a 700D and I am planning on installing ML and I'm about to order a card. If I get it straight, despite CBr, RAW, etc. the camera won't be able to go upwards of about 40 MB/s?

And btw, which card do you recommend? Right now i'm between a Sandisk Extreme 60 MB/s and a Sandisk Extreme Plus 80 MB/s :-\? Those are read speeds, advertised write speeds are 20MB/s less on each.

The 700D is hardware limited to 40MB/s.  Doesn't matter how fast the card is, that is the maximum limit on that camera.

You probably want to ensure your card is faster then this limit, as this ensures you always reach that hardware limit. 
I'm a little impatient, so I get the fastest card I can afford, for reduced transfer times from card to computer.

Hello all, I'm planning to buy a 50D for raw. The first that came up to my mind after seeing te prices of CF cards, was why no one is using SD->CF converters? SD cards are way cheaper and get easy to 90 write and read. example : Samsung MicroSDXC Pro 64GB + SD-adapter. Another pro of it, is it's flexibility to use in other devices like small camera's and even smarthphone. Is there someone who wants to test this out?

Please do some research on the web.
You will have a hard time to find hard data for most of those adapters.
You will need at least UDMA-6 covered by CF interface and UHS-I for the SD slot.

And I was not able to find a test saying "Eureka! It works at full speed!". What I found looks like this: http://goughlui.com/2014/07/31/tested-two-secure-digital-sdsdhc-to-compactflash-cf-adapters/
Most tests I found are outdated.

I just got 2 of those Lexar 1066 64GB cards and they are both almost identically peaking at 63mb/s when running in-camera benchmark.
In Playback mode they get a bit above 80mb/s - similar to the results I get from them in "AS SSD" and Chrystalmark.
Seems that they are too fast to be fake but also too slow to be real - any thoughts
Actually, performance wise, it seems to be closer to my Lexar 32GB 800X than I'd like :(

80 MByte/s is quite too slow for this type. Any chance your reader is sub standard? Sometimes virus scanner may slow down benchmark tests. Disconnect from web, deactive antivirus software and re-run benchmark tests.

Initial thoughts: The KB card seems to benefit from "warming up" whereas the Lexar is more constant.
I find it interesting that the READ speed on the Lexar is is on par with the KB whereas the write speed is horrible. This reminds me of my Lexar 800x which similarly benches at 140mb/s read - 47mb/s write
[All cards tested with identical settings, eg. clustersize, filesystem, camera settings ]

Controller SM2236AB is a bit outdated.
Turn off Global Draw, activate benchmark and press PLAY pretty fast.
Post results, please.

EDIT: Or you can skip that part, return card to dealer and order one more up to date (SM2236AC or newer).
Just learned that different controller types for this card seems to be significant.

@ Walter
Cards are still crunching, my initial observation however is that with GD off in Playback mode Sequential write is around 107mb/s for the Komputerbay card and 80-81mb/s for the Lexar.
I guess that now I know why they where cheap (91$ per card)
Thanks alot for your analysis and swift help Walter.
I guess I am sending them back and in the future I will remember to pay attention to revisions and controller versions.

Any advice on how to identify controller versions based on card revisions or serial numbers?
I have been talking to 7 different sellers as well as using my inferior google skills to no avail :)

I'm sorry but I can't tell for sure.
It is said H2testw is able to identify controller types if some conditions are met. USB is blocking access on this level and the CF-cardreaders I own are that type. SD-card slots on those netbooks/laptops I tested won't do either.

Once there was a site devoted to heavy-duty test routines but he stopped some years ago.
http://www.hjreggel.net/cardspeed/index.html
Seems to use EOS cam right now ...

If there is someone out there successful reading controller type by H2testw I would be happy to hear about his environment.

When does the Magic Lantern firmware v.2.4 for the canon rebel t3i comes?
I don't want to install nightly builds, because im afraid that my camera breaks...

Top of page -> User Guide -> FAQ -> Last question (section Troll Questions)

With the recent update in nightlies for ML -- curious if I should run another BM test w a fast CF (KB 128GB 1066x) with 113 build from 3/2 for comparisons with previous BM's?

I bet you won't see reproduceable differences. I you have time you may prove me wrong.

That's why I asked.

But I'm afraid you're right there's really no differentials other than pushing .3-.5 MB/s slower than last time I did this.

Guess this is to be expected from 'wear & tear' (this KB card was 5-6 months) on the CF cards.... Correct?

Differences that low in a single sample test don't have any significance.

Okay -- Thanks!

Thanks for your advice
The 95.8 MB/s record you reached with the KG 1066x rocked my socks too!! . I bought this SanDisk few weeks ago. Actually I heard lots of mixed up negative and positive thoughts about KB cards in and out of forum. some talking about the impressive speed, some mentioned it gets hot and unstable...some said it works well and some said it doesn't work at all! add lots of corruption reports to that. these completely opposite comments made me consider buying something more truthworthy and reliable like SanDisk or Lexar. (i saw this article http://www.cinema5d.com/guide-raw-on-a-5d-mark-iii-magic-lantern/) and saw zero failure reports on SanDisk cards.

I'm in "Iran" and here the fast CF cards like SanDisk are double the global price(no KB here); so i had to purchase it abroad. there is also lots of limitations in ship so if the product i receive doesn't work there will be a nightmare of sending it back and getting a new one. that's why choosing the most reliable card was the only way for me. I couldn't risk.

Absolutely and I totally understand. I was on the same boat for years and once I purchased several KB's man I was floored and felt like a fool for not getting them sooner.

128GB 1066x seems to be the sweet spot for the 5D3, IMHO.

How many of the purchased KB cards worked? How many failed?!

Have you ever encountered any failure report on these KB 1066x cards?

Ps. In the previous posts you have mentioned you reached 103-106 during 3.5k! Is that with card spanning?

I've bought 3 so far and all of them have worked as advertised. It was surprising to me because I was expecting to send one back based on mixed reviews.

Guess I got lucky?

As for 2.5k (not 3.5k) crop-mode... I think it was without card spanning but I could be wrong and will double check.

@DeafEyeJedi

would you please share your experience with 3.5K ? (3584 x 1320) ...ever been able to shoot more than 2-3 seconds? in 23 or 24fps ?

I want to start trying raw video with my 5D Mark III. So far I have only SD cards and I want to buy a CF card for raw video.
I read mixed opinions on the forum, and recently the prices went down for brand names (Lexar and Sandisk). I wonder what's the current best choice from a price/reliability point.

Should I buy a Komputerbay card? Is there a difference in quality or reliability between Komputerbay 64 gb cards and 128gb cards? What speed? 1000x, 1050x or 1066x? I guess there must be users who have by now a long enough experience with them.

Are Lexar Professional 1066x or Sandisc Extreme Pro better than Komputerbay?

Thanks.

So far, I've been successful with 1066x 64gb from Lexar and 160mb/s 128gb from Sandisk. Though, none could do what I lusted fullhd @ 30fps, Lexar did it with help of spanning across CF+SD (LCD should be disabled via hack). 24fps worked fine for both. In fact, when hand held, I may shoot 1920x1152, to have extra space for software stabilization.

Will just testing my all my CF Cards (Lexar 1066x & 1000x) before I go and cover a outdoor Street performer festival  today, and to my amazement
my Lexar 32GB 1000X would not boot on my 5d2. Camera say needs to format, and in the card reader on PC same thing need to format, but can't say it only 32MB ! I guess the card is done, It was my fastest  :-[ .  I guess the Lexar Professional line have 10 year warranty , I guess I have send it in.
Make sure you test your cards , you just never know when that card will fail.

I agree. Thanks for the friendly reminder and today I just tested them all out just for the hell of it. You're a good influence and unfortunately one of my KB 128GB 1066x is currently showing a stuck red pixel at the same spot... Haven't seen this in awhile (years) and don't remember what's the best solution to remap them out or do I need to send it in for a replacement (I think KB has lifetime warranty)?

Just got a 7D and I am a total raw video noob..
Read through this and many other threads, I'm still torn!

What should I go with?

64gb Lexar 1066x or 64gb Komputerbay 1066x?

Also are people still having issues with the 128gb KB cards?

Hey guys, I'm new to RAW video too and have a couple questions. I'm about to buy a CF card for my 5D3 and need some guidance

Looking through the forums I see a lot info and would like some clairification

1) Is komputerbay 64gb 1066x the best card for raw out there?

2) Is the Lexar 64gb 1066x the same performance? (More stable, I think I read?)

3) How come no one talked about the Lexar 128gb 1066x, is it no good for RAW? Can the 5DM3 use a 128gb?

4) last question, I see the Lexar 64 and 128gb at 3400x on Amazon.ca but haven't seen anything about them in the forums? Won't those be the best?

I understand these are very noob questions but I'm having trouble finding those specific answers in the forums

Appreciate the help thanks!

4: Those are CFast cards. All ML supported cams are incompatible.

Okay thanks that's definitely good to know. And the Lexar 128gb 1066x?? Any good? Is the komputerbay better?

Hope devs have some tricks left up their sleeves to overcome hardware limitations of file writing on 6D.

No, ML devs are not up to messing with Canon's hardware.
You get slighty higher numbers in Play mode (press Play button after starting benchmark) but you will be limited to about 41 MByte/s in write mode which is good for about 720p24 in RAW/MLV (continuous) or higher resolutions for short clips.

Thanks for your reply Walter. Even 10 seconds of a 1824x764 RAW footage at a time is a godsend for a 6D :) Thanks to the ML team for their sleepless nights and enormous work.

It appears Lexar 64GB Professional 1000x UHS-II SDXC Memory Card has issues with ML (Nightly.2015Nov07.6D116). The card randomly becomes unreadable (lost partition) and requires full format. Everything gets lost including ML files on the card.
Windows error message says: "... is not accessible.
The volume does not contain a recognized file system.
Please make sure that all required file system drivers are loaded and that the volume is not corrupted."

I tried restoring the partition, but the software I have could not even find the drive.

ML is solidly stable on my other card - WinTech Elite 32GB.
I wonder if the issue is related to UHS-I U1 vs UHS-II U3.

Here's a report for 6D, SD card, WinTech Elite 32GB in Play mode:

(http://static-malinadz.com/ml/WinTech_Elite_32GB_95-50MBs_24fps_play-mode.jpg)

Is it worth getting UHS-II 1900x cards for the sake of maximizing write speed consistency, e.g. getting close to average 43MB/s?

You won't see more than 42 MByte/s write speed and this is a benchmark just optimized for maximum card interface performance. Don't expect recording to go beyond 38 MByte/s without hickups regardless how fast the card might perform here.

On UHS-II: There is no Canon DSLR supporting UHS-II. All cards will used in their UHS-I mode. Some UHS-II cards do quite good in UHS-I but some just don't. Examples:

Panasonic MicroP2: About 38 MByte/s in write mode
SanDisk UHS-II: About 46 MByte/s in write mode.

See http://cameramemoryspeed.com

Walter, thank you for the explanation & link.
What I'm curious about is whether those faster cards (1900x) can handle let's say 36MB/s at all buffer sizes. UHS-I cards can't, according to the posted in this thread results.

7D on SanDisk Extreme PRO 64GB (1067X, 160MB/S)

Been using KB 64 1000x from one of the first batches since ML RAW came out.
Need some more cards now and noticed that Lexar 1066 64GB appears to be cheaper (~110$) than the cheapest 64GB x1000+ KB cards (~135$) (I am in Copenhagen and all the cheap KB cards are sent from outside EU meaning that they are subject to high import tax/VAT)
At 110$ vs 135$, have I missed a reason to not go with Lexar?

1000x cards are actually more expensive than 1066x cards. So why do you want to buy something for a higher price with less performance?
And can't you order via Amazon Germany/UK?
KB 64 GB 1066x: 59€
KB 128 GB 1066x: 93€

Thanks Walter, had a feeling that I was missing something :) Amazon.co.uk sells the KB 64GB x1000 at 55GBP incl. shipping so that seems to be the best deal I think.
I have been rather inactive on the forum in 2015 and this thread leaves me wondering if the KB x1000 64 really still is the king of CF for MLraw? The 128GB x1066 are rather cheap but I seem to remember that they were less stable than the x1000?

Amazon.co.uk = 75 Pound (107USD
Amazon.com= 93 USD
Apart from being way cheaper than eBay, 85USD is by far the cheapest I've ever seen these :D

5D3 1.2.3 on SanDisk Extreme PRO 64GB (1067X, 160MB/S)

Hello this is my benchmark with 128gb Komputerbay 1066x on Canon 5d2

(http://i65.tinypic.com/28al46c.jpg)

And this is not enough to rec 1856x1044 RAW
What I should do? Ask for a refund? It is not too slow?

The best USB 3.0 cardreaders will give you about 150 MByte/s in write mode for this card. Cam's card interface is the bottleneck in real life.
You may see slightly higher numbers by pressing PLAY button after starting benchmark. It will show you what the cam is able to do but not what you can expect during recording. Overhead ...

Ok I understand this point but I thought at least be able to rec with this card 1856x1044 continuous. So the problem is the camera can't afford this amount of data or I could get this video resolution with other faster card?

This one is among the fastest cards you can get. I repeat: The cam's card interface is your bottleneck.
Shooting continuous with 24 fps in this resolution requires about 77.6 MByte/s and you won't be able to match the numbers.

75MB/s is the limit the 5D2 can sustain  , but can record in busts to 79MB/s for about 20-30 second
the only way is to use .raw (legacy raw no audio & metadata) should be able to maintain 1856x1004 @ 23.976p A.R, 1.85:1
At Least from My 5D2 on Lexar 1000x & 1066x tests show

If you what audio then you need to choose a smaller frame resolution
I use 1856x928 for long recording & scale it to full HD if needed

I can go with the same resolution sizes. Thanks Walter Schulz and reddeercity! Seems work perfectly!

If so, is there any sense in buying Lexar 1066x over Lexar 1000x for my 7D?
I understand 1066x has slightly better write and read speeds, but almost all benchmarks are made using 5D3, which also has higher write limits.

My point is: will 7D benefit from choosing 1066x at all?

I'm aware 1000x is no longer produced, though sometimes still available at the market.
I can get 32GB 1000x in the price of 16GB 1066x.

Thanks.

Wow!
So the oldie 7D can go a little faster than the suggested 80MB/s in the ML RAW Capacities charts.
No point in saving money on CF card, then.

Thank you very, very much.

Just for reference, I completed this benchmark on a 650D some time ago...

I've read a lot here and through the web and I'm far away from being through. I know that many aspects influence the actual write speed during shooting. However, to boil it down to one question:

would you recommend 64GB Sandisk Extreme Pro 160mb/s or 128GB Sandisk Extreme Pro 160mb/s? Is it worth to get any of these if the camera can't keep up with the cards writing speeds?

The benchmarks in this thread show similar speeds:

http://www.magiclantern.fm/forum/index.php?topic=12630.msg144584#msg144584 vs http://www.magiclantern.fm/forum/index.php?topic=12630.msg164489#msg164489


No card really topped the 100mb/s in writing speed since it seems that the bottleneck is the camera itself?
Then I read that the 128GB is »the best« in terms of writing speed with the right settings of course.

Anyway, ML tells me that I need at least 104mb/s for the resolution I want. I've tested with my KB 64GB cards and they stop after 5-10sec. Writing speed in benchmark are about 90-92mb/s.

Did anybody had the full writing speeds or at least over 100mb/s with the fastest Sandisks or Lexars?


Thank you!

The bottleneck is the camera, limit is around 90MBps, so a fast card is needed. But you won't get 104MBps needed for continuous recording of the resolution you desire, yet you can get small amounts of recordings like you are experiencing, this is normal behavior.

Hello, please pardon my ignorance or lack of technical knowhow but I've just installed ML on my 700d. I have a Sandisk Ultra 80mb/s card but could only get lowest quality constant raw video to record. Anything decent would record abbot 5 seconds before fail.

I then bought a Sandisk Extreme 90mb/s class 10 v30 64gb thinking this would work but it still only gives me a few seconds.

I don't understand all these black screenshots of benchmark tests, which card speed will work for me?

Thanks

Interface limit for 700D is about 40 MByte/s. Card needs to be formated with ExFAT option. Cam should do that on its own for cards > 32 GByte but you should check that using your cardreader.

And without running benchmarks you are not able to tell if the label tells the truth. Flash fraud is widely spread.

I understand that the "bottleneck" is the camera as far as write speed, but I wonder, can someone explain to me if this is solely a hardware limitation, or if there is potential room for improvement via ML? Thanks.

Theoretical bandwidth limits for SD-card interfaces (UHS-II excluded):
http://www.hjreggel.net/cardspeed/cs_sdxc.html
For 700D it is 47.68 MeByte.
5D3 is using UDMA-7 CF-card interface and that will do (theoretically) transfers up to about 159 MeBytes.

Build used?
You will find a file BENCHx.PPM on card root. Convert it to PNG or JPEG, upload it somewhere and link it here, please.

Hello everyone.

I've ordered komputerbay 64gb 1066x cf card from amazon. I want to use with sd card for the best quality. Is there a scheme or tutorial to show how should the settings be?

thanks.

Just bought for €25+shipping this sdxc card - Sandisk extreme pro, because I was curious about the claimed speed of (up to) 170MB/s


(https://i.ibb.co/xz0BpJ3/sandisk.jpg) (https://ibb.co/xz0BpJ3)


I've tested with Danne's build crop_rec_4k_mlv_snd_isogain_1x3_presets_2019Apr09.EOSM202
and achieved speeds around 56 MB/s in the 2.5k preset.
In the cardreader Transcend TS-RDF8K I've run the blackmagic diskspeed test which were 75MB/s Write And 79MB/s Read, and used also the F3X soft to test the Card, which test it passed, however the sustained writespeed was around 72 MB/sec.

Even this card doesn't perform as advertised, I think I will keep it.

170 MByte/s mode is proprietary SanDisk. SanDisk doesn't keep it a secret this mode is available using some of their own cardreaders only. And it is read rate. They are a tad slower in write mode compared to fastest "conventional" cards supporting UHS104 mode only (when used in devices following SD Association specs).
See https://www.cameramemoryspeed.com for details.

F3X isn't build for speed and will not tell you card's top performance.

Is it gonna make a difference if i buy this uhs-ii card for canon M ?
https://www.cameramemoryspeed.com/reviews/sd-cards/sony-m-series-128gb-sdxc-uhs-ii-memory-card/
Currently i have canvas go 64gb with 45write speed but from diskmark test it shows 69-70mb.
I cant benchmark in cam in current M build with sd hack cause theres no bench.mo and old one is not comaptible.

Pretty slow for an UHS-II card. Write mode maxes out at about 100 MByte/s in UHS-II readers and 81 MByte/s in UHS-I.

Cannot say how UHS-II cards in UHS-I compatibility mode are compatible with overclocking a la ML. Anyone tried?
Maybe a1ex or nikfreak are able to tell.

yeah thats what i was interested with, so it wont even hit uhs-i limit of 100mb in its uhs-i mode?
If its just 81 mb then just 10mb more than what i have at twice the price.
So is there some known sdxc card that will hit maximum limit of 100mb writing speed on canon M ?
I dont want to buy card thats gonna be crippled by camera anyway and costs 2-3 times as much while i gain 30MB.
I chose slow one cause i read about uhs-i limit being 100, so no reason to buy faster ones anyway for my cam ?

No.

This is the fastest one within pure UHS-I specs according to SD Association (without SanDisk's proprietary wizardry): https://www.cameramemoryspeed.com/reviews/sd-cards/sandisk-extreme-pro-95mbs-uhs-i-64gb-sdxc-memory-card/

Thanks Walter i think ill buy it

Canon M
Current card SanDisk Extreme 80MB/s U-1 Class-10 64GB (SDHC card)

Looking to buy a new SDHC card and contacted Canon about getting a newer higher speed card for the camera. Canon customer service replied with, "Good luck, Bro!"  (Not the exact wording...)

So, my question is; for those using ML and the Canon M... has anybody had better results with a higher speed card, or should I just stick with the same card because it is dirt cheap to do so?

I skimmed the last page here and see someone in the above threads is using a 95MB/s U-II (I'm supposing that all these SDHC cards are backward compatible).

Current card SanDisk Extreme 80MB/s U-1 Class-10 64GB (SDHC card)

Picture, please!
Pretty sure there is no card matching this description. "U-1" does not exist, it's either UHS-I (interface type) or U3 (UHS speed class). If it is indeed U1 you should get a faster card easily ...
"U-II" does not exist either. Because there is no U2 designation it can be determined you meant to write UHS-II. But there is no Sandisk card with UHS-II interface and 95 MB/s written on label.

Cam's card interface is SDR50 or DDR50 -> 50 MByte/s transfer rate (theoretical). With overclocking we get transfer rates above 65 MByte/s (benchmark only, not possible in RL recording) compared to about 38 MByte/s write rate for continuous recording.

Do yourself a favor and benchmark your card with a decent cardreader and programs like CrystalDiskmark (Windows) or BlackMagic Disk Speed Test (macOS).

Browse www.cameramemoryspeed.com for some benchmark numbers. For UHS-II cards you have to find out which cardreader does not support UHS-II to get the numbers for UHS-I compatibility mode.

Just benchmarked two cards for my EOS M2:

Using Transcend USB3.0 card reader and CrystalDiskMark:

SanDisk Extreme Pro 170mb/s 128GB = R 94mb/s and W 84mb/s.
*No problem running continuous 14bit lossless MCM Rewired at 1736*976

SanDisk Extreme Plus MicroSD/Adapter 170mb/s 128GB = R 93mb/s and W 85mb/s
*No problem running continuous 14bit lossless MCM Rewired at 1736*976

For anyone who is a member or knows someone, the 128GB Extreme Plus w/adapter is available in a 2-pack from Costco for only $45 (USA) (for both). Great deal.

Are you serious? Even the MicroSD while using the adapter doesn't bottle neck the writing speeds at all? I'm surprised...

Will definitely borrow one from work and give this a test run just to see. I mean that is def a great deal from Costco.  :-X

A Micro-SD adapter contains just a few millimeters wire. Doesn't offer a lot of opportunity to mess things up IMO and according to my limited experience ...

I once read about adapters

The Extreme Plus MicroSD 80 is ranked just behind the Extreme 95 Pro in the 6D memory test on the CMS website. That's why I thought it was worth getting the Costco 170. I assume they used an adapter for the test.:

QuoteSpeed tests with and without the adapter in readers with both slots provide virtually identical results (microSD to SD adapters are simple pass-though devices).

The microSDHC version of the Extreme Plus outperformed the standard SD card version that was previously reviewed.

...In camera tests the 32GB Extreme Plus microSDHC posted some impressive results. In some cameras it is among the top performing cards.

New to the forum, here to post some findings. Just got my first Eos M and I have some sd/micro sd cards laying around, before I buy a new one I thought I would test them out first.

Samsung EVO select microsd 128GB,   160Mhz gives best results @ 54.5MB/s, which is enough for 1080p at 14bit, which is the only mode I need, this card runs about $20 on amazon.
Samsung EVO select microsd 256GB,   192Mhz gives best results @ 56MB/s, which is enough for 1080p at 14bit, this card currently sells at $35 on amazon, I got it when it was on sale at $25.
sandisk extreme Pro 95MB/s 32Gb,      192Mhz gives best results @ 44MB/s, just about barely enough for 1080p at 14bit.
SanDisk Ultra 64GB MicroSDXC, this card is a no no, it barely goes above 20MB/s, so not enough for magic lantern.
Patriot LX Series 64GB, slightly better than Sandisk Ultra, goes to about 28MB/s, still not enough for magic lantern.

So shooting at 1080p 16:9 at 14bit, you are gonna need at least 41 MB/S writing speed. A 64GB card is gonna give you around 20minutes of footage, 128GB 40min, 256GB 80min and so on so forth. Based on my personal experience, a 8-10 hours shooting day(story based short film), I usually get about 60-75 mins of actual footage on camera. So for me, 256GB is the minimum.

So if you are like me looking for a cheaper alternatives to the much praised but more expensive SanDisk Extreme PRO, samsung evo select is a pretty good contender, they are not as fast as Sandisk extreme pro, but  good enough for what I need.


Currently I'm waiting for a 256GB Samsung pro plus full size SD card to be delivered,  I got it when the price is marked down to $30 for 256GB size, not sure it's temporary or permanent. It's supposedly designed for 'professional' use so I expect it to be more durable and writes fast than the consumer grade EVO select. I will report back when I receive it.

Samsung Pro Plus SD     for EOS M

Ok, got the Samsung Pro Plus sd card today (not the micro-sd version)

It's slightly better thatn evo select micro sd version but not by much.

160Mhz   writes at 54.8MB/s
192Mhz   writes at 59.7MB/s
240Mhz   writes at 19.7MB/s

so 192Mhz is the best fit. And since it's marked as 'professional', hopefully it will be more durable than evo select version.

My location is in China，I got the Samsung Pro Plus sdxc 512G tested today，very disappointed.This card will drop speed on eosm with sd overclocking .
ML version is "crop moon"april 18.The 240hz got very good result on either benchmarks and real raw recording at first.But after a minute or two,the R/W speed dropped to 20MB/s range,resulting a halt in recording.Do a off and on of the camera,the circle repeated.Changing the mode to 50 or the speed to 192MHz will not solve the problem.
By changing the buffer size in benchmark test ,I notice when the buffer size is bigger ,the recording speed seems to be normal,when the buffer size is smaller,the speed dropped to 20MB/s.
I also replaced another version of sd overclocking module file,it seems to be a little better,but the speed drop still existed.I will return the samsung ,get another card and continue to find the best priced card for ML.

Please copy fineprint on card backside. You will find a string like MB-MD512K
This will help cornering your issue.
Benchmark numbers using a cardreader are ok?
Also a card integrity test using h2testw (Windows) or F3 (or derivates with GUI) for Linux, macOS may be in order.

I've seen two posts in the past that people are talking about the "pro plus"compatibility issues,One post showed the same speed drop issue,a developer tried to fixed in sd uhs.mo,the user test the new modual,reported to be fix,but not in my case. The other post said this card (maybe he's talking about the sd version of pro plus) is good at benchmarking but very bad for long recording,that I think he's talking about the same issue as mine here.
I bought this card from the official Samsung store on taobao.com,so I didn't even think about the fakes or other quality issue of the card,so I don't even tested it on computer.I don't know there's anything I can mess with it and get it to work,so I just give up and return it to the store,they have "7 days  return with no reason policy".I'm gonna just buy the sandisk extreme pro 170MB/s 256GB which is a little bit expensive than the 512GB pro plus, but I don't want go into trouble again. :'(256GB is able to store over a hour of 1080p raw video,so it is enough for me but not "do whatever I want" capacity.

Last card I'm buy is Samsung Pro Plus 256 gb micro SD version
Got around 80mb/s with 240mhz hack

Don't just do a few times of benchmarks,you should do a lot of real shootings,after all,it's a camera.I returned this card ,it's garbage.Now I 'm having a SanDisk extreme pro U3 C10 V30 A2 micro sd card,256G,very good price,almost half the price of the equivalent SD version!
Actually,I'm typing this thread while testing the new card with eosm.I keep the camera recording with different settings,recording for long time,strange things have happened,including speed droping.NOT as stable as my old extreme pro 95MB/s SD card!
More real testing!!
......Oh no,this sandisk will drop speed about 6 minutes of recording ,then have to restart the camera to keep shooting!
More testing....
FORMATED the card using canon camera low level formating,record again,about 30 minutes have past,no droping speed anymore!! This card is as good as sd versions of extreme pro!
