Hi guys
We have to find the best solution for 6D raw recording, theoretically we are limited to 50MB/s.
In fact there is very hard to find a card which exceeds 40.
There are many information about write speeds in other topics but here I would like to gather all of them.
1. Sandisk Extreme 45MB/s 64GB -37,5 to 39,7 peaking sometimes to 41,5 for half a second
2. Sandisk Extreme Pro 95MB/s ?
3. Lexar Professional Class 10 600x UHS-I SDXC ?
4. Delkin Devices 64GB SDXC Memory Card Elite 633x UHS-I ?
5. Kingston 64GB SDXC Memory Card Class 10 UHS-I. ?
6. Patriot SDXC UHS-I U1 64GB ?
7. Patriot EP Pro SDHC 32GB UHS-I 90/50 MB/s -37,5 to 39,7 sometimes 41,5 for half a second (almost the same as no.1)
Patriot EP non pro... up to 32MB/s... usually 30-31.
Samsung 64GB UHS-1 30MB only... card rated at 40, crap.
Has there been any more research on the fastest card for the 6D?
I currently have the Sandisk Extreme 45MB/s - 32GB and I was looking at getting another one. Is there any advantage to getting a Sandisk Extreme Pro 95MB/s? There does not appear to be any real advantage since the Canon 6D is limited to 50MB/s.
Any new information available?
Thanks
I have ordered patriot PRO 90/50 32GB. It is in theory 50MB/s write speed so seems to be optimized only for 100mhz frequency. Sandisk 45 has theoretically 5MB lower speed, sandisk 95 is optimized for 208mhz which may slow down 100mhz (but not sure of that, just thinking)
I think somebody from this forum had such a card and there wasnt much difference from sandisk but I cannot find this thread so I thought i should give it a chance.
Are there any other cards with claimed write speed 50MB and not 40,45 or 90/95?
I have ordered a Sandisk Extreme Pro 32Gb 95m/s. I should have it in a couple of days.
I will let you know as soon as I can start testing it how it goes.
Reading another thread in this forum i've stumbled upon this page, which was linked from another user: http://www.gavtrain.com/?p=2617
Does anyone have feedbacks for the Transcend cards? The 32 gb on amazon is only a couple of euros more expensive than the Sandisk, so I was thinking to give it a chance...

Let's cut to the chase: no way! >:(
It is doing the same as sandisk 45 at best, sometimes is slightly worse :(
All what I was hoping was 2-3MB/s more
Below i put comparison with sandisk 45 64GB - tested with [113] BigMemPhoto
Sandisk Extreme 45MB/s 64GB Patriot EP PRO 90/50MB/s 32GB1728x736 >>> 342 frames hack OFF, hack ON - 357 frames---------------the same 342 frames but no difference Hack on/off
1792x752 >>> 280 frames hack OFF, 280 hack ON -------------------------worse with hack off >>280 H ON, 266 H OFF
1792x672 >>> 421 hack OFF----------------------------------------------------worse 406 H off
1664x704 >>> 528 frames hack OFF----------------------------sometimes better, sometimes the same, 544, 528, 544
I think it gets the higher write speed - 39,4-39,9MB/s
1664x624 >>> 1548 frames hack OFF-----------------------------------------no comment, 1368
One good thing is that patriot is NOT MUCH worse than sandisk so I will have additional 32GB for raw footage.

Yeah, but they also tested sandisk 45 and according to the test results it should give actual 43 MB/s. I have never had such a write speed in 6D! I think, that the bottleneck is somewhere else and cannot continously do more than 40. But really I hope I am wrong.
Maybe someone will buy this card and we will see.
It never hit that on the write test either did it?
Sucks if max is 10MB/s below the standard. I'll try when I pick the sandisk today or tomorrow.
Ok I have my Extreme pro to test right now but I don't have an extreme to compare it to. I don't really know how to get a 255mb buffer size like you Kgv5 so my results would be different from yours... Could you set your memory to 151mb for testing purposes, temporarily? Thanks.
Edit: Well on this test you did before:
"1664x624 612, 648, 630 (with hack on - 730, 738, 756) upscale 115,5%"
I got 720 frames without hack mode on... Probably would get about 830+ with hack mode on. I guess it is a bit better lol.

sandisk extreme 45MB/s 64GB 151MB buffer, 1664x624 hack off-- 648 frames
seems that there is no difference :(
To activate 255 buffer:
turn cam off
switch to stills mode
turn on cam
turn on LV
go to canon menu
go to fourth tab
long exp. NR - OFF
high ISO speed NR - NR (multi)
turn on ML menu
third tab from the right
go down to free memory
check - should be 255MB
remember, that first recording always is shorter somehow, so press record button, let the camera to record couple of frames, press record off.
Now you are ready for full 255MB buffer recording.
So let us know how many frames do you have with resolutions from my previous posts, thanks :)
Hi and thanx KVG5, I was having the same problems than xNiNELiVES, got a sandisk extreme pro 32Gb to try but I didn´t know how to get all the buffers. ;) Cheers.
I´ll do some test I will report them asap.

Kgv how could it not be better when I got 100 more frames?
hack mode is better depending on frame size.. but doesn't seem worse.. sometimes GD off is better too.

Yeah I will ASAP. At school lol.
One more question though: do I have to set the picture quality to jpeg?
Yep, jpeg, no raw.
Quote from: kgv5 on June 06, 2013, 07:54:07 PM
Yep, jpeg, no raw.
I don't have the camera to double check but last night when I switched to camera mode (stills) and changed from RAW to jpeg the red light by the SD card door would not stop flashing. Is that normal?
From the results above it looks like the Extreme (not Pro) 45MB/s is the second best choice by a very small margin. With the write speed slightly better on the Pro but not enough to justify the price. I was hoping that the Patriot EP Pro SDHC UHS-I 90/
50 MB/s with the 50 MB/s but it appears to be hitting the hardware write speed limit.

Yeah, exactly, I was hoping that too.
But one thing is strange - if top speed is 40 how can we have 41-41,5 for a second or so sometimes (both sandisk 45 and patriot 50). Especially in the beginning sometimes I have 41-41,5 (for about half a second) and then it drops to 37-39. Maybe there is a way to sustain this higher speed for just a little bit longer.

Yeah I will ASAP.
xNiNELiVES, could you please check especially 1792x752 with working LV and force left? I have 280 frames, speed 41 for a half second, than dropping to 39-39,5. This res is very nice, 2,39:1, 107,5% upscale and quite usable 10-12 seconds of footage. I wonder if you could get some more frames with sandisk 95.

My only
guess would be that the buffers are more available for moments at a time which is why we're seeing a spike. What a challenge and hats off to the development team to get us this far. ;)

Ok well for some reason with the 7x32mb buffers I only get 183 frames. I consistently get 38.5-39mb/s never 41 though.
What Autoexec are you using, etc?
now I have the newest build, [113] Just small Changes with H264inis but I get the same results also with previous [113] ETTR-MemDontclick and [113] BigMemPhoto. This 41 is only for like a half a second in the beginning, normally 39-39,5. Other settings: sound sync beep, global draw off, framing force left, preview auto, start delay doesn't matter, memory hack on.
the first recording gave me 181 frames, second- 281 frames. From time to time I get also 266 frames.

Oh! Fuck why didn't I listen I forgot about how it's shit at the start, I'll retest lol.
Edit: OMG i was at 30 fps too!
Ok Well I retested twice, I get the 41.5mb/s spike and then it goes down to 39 then it went back up to 40 for a second. Still only got 280 frames.
Do you know what the difference is between 23.976 and 24p? Well besides the obvious difference, I'm talking about functionality differences. Why is it such a important number compared to 24 hundredths of a second difference in a frame.
I have been doing some test with small changes & new inis using a sandisk 32Gb 95mb and is it constant 280 frames at 1792x752 and one time recording with crop factor 295frames, so I think it is pretty much the same as the others, doesnt make much of a difference between the 45mb and the 95mb sd cards.
Have to do something w/ the 23.976.. its calculated wrong and doesn't give normal timings with high shutter.

I googled it. What it is is that when film gets put on television or something of this sort, the sound is pushed off. With 23.976 the audio is in sync.
Overriding 23.967 over 30P is supposed to give 1/3000 or at least 2000 shutter. It does on other cameras.
Whats the best cluster size to use on these sd cards? Right now I'm using 4096.
How about the maximum size allowed for 6D SD cards ,128GB could be a good solution for recording raw ?
Anyone tried in decent conditions 128GB (Transcend , Komputerbay ,etc) ?
thanks,
It appears that the final conclusion is that the Sandisk Extreme 45MB/s SD card is the fastest for the Canon 6D ... correct?

Best choice is the 45mb/s. It ties with other faster cards because the camera is hardware limited.
Good news!!! There's a new line of high speed SD cards from Toshiba. Here's the press release:

http://www.engadget.com/2013/07/16/toshiba-exceria-pro-sd-cards/
And its not going to have any improvement over the sandisk extreme because the camera is limited to only 41 mb/s.
How about Toshiba Exceria Type 1, I heard it has a 90mb write speed, did someone test that cards?
There is a hardware limit, slow SD drive controller. Card speed above 40-41 MB/s doesn't matter.
Newbie question...
I presume the above goes for shooting RAW video on the 6D too - not just photos?
I have 4x Scandisk Extreme 32GB 45MB/s cards and was wondering if I needed to upgrade to some very pricey ($119 each) ScanDisk Extreme Pro 64GB SDXC 90MB/s cards. Based on my reading of this thread the Extreme Pro 90MB/s cards often no/minimal performance benefit - their speed being limited by 6D hardware restrictions (max speed achievable 40-41 MB/s).
Thanks to kgv5 and other posters for saving me $$$$$
Yes of course, these write speeds go for everything.
I use ScanDisk Extreme Pro 32GB 95MB/s cards and get ~2600 frames (~01m:40s) 1664x640, 40.1 MB/s. Card format exFat with 64k cluster. Build DualIso-FullPack (2013-08-11). Hack ON, extra hack ON. But enable buffer to 255 failed, it remained 151 (( Can something not so doing. With 255, it will surely be even better result.
Changing the settings, exposing the "raw" or "jpeg", to photo mode turned out that it also affects the length of recording video in raw. In a previous post I wrote that managed to get about 2600 frames. In the case was put on the "jpeg". Setting the "raw" I got a recording duration in the 5800 frames, or 04m:02s to fill the buffer and auto stop recording.
And, accordingly, the file size is about 5 GB. And raw2dng unpacks only those that up to 4 Gigabytes. :'( :'( :'( Or is there another raw2dng, which unpacks large files?
Use exfat or combine the R00 files with the raw.

Not very understand you. I only month as ML use, not all yet understand.
Quote from: kgv5 on June 06, 2013, 04:00:16 PM
To activate 255 buffer:
turn cam off
switch to stills mode
turn on cam
turn on LV
go to canon menu
go to fourth tab
long exp. NR - OFF
high ISO speed NR - NR (multi)
turn on ML menu
third tab from the right
go down to free memory
check - should be 255MB
remember, that first recording always is shorter somehow, so press record button, let the camera to record couple of frames, press record off.
Now you are ready for full 255MB buffer recording.
So let us know how many frames do you have with resolutions from my previous posts, thanks :)
I have not been managed to activate it in this way. (( How to do this more?
Set quality to raw, use the memory hack in Movie mode, it will auto enable 255 when it starts up by going in and out of LV. You should see "busy" on the screen sometimes, make sure this feature is on in the module.

I've been testing out the 6D port (from this post (http://www.magiclantern.fm/forum/index.php?topic=5530.msg37766#msg37766)) using my SanDisk 45MB/s Extreme card and can only seem to get around 100-140 frames.
Can I ask what your exact setup is to achieve 280 frames at 1792x752? Would be great to get results like that.
Tried again today, can only get 40 frames at 1792 now. Weird.

Are you sure you've got an authentic Sandisk card? Esp. with this brand there's said to be a very high percentage of fakes which have slower write speed... you should try to do a card benchmark on a fast usb interface to see what your card is capable of at all.

Yeah my cards are authentic. I didn't have the image quality set to RAW (doh) setting that that got me back to around 140 frames. Any idea how to get more?
This is what I do to setup (using all the ML defaults untouched to start):
• SET IMAGE QUALITY TO RAW
• TURN ON ML MODULES
• SET RAW VIDEO TO 1792x752
• TURN ON VIDEO MODE
- Card warm-up: OFF
- Memory hack : ON
- Extra Hacks : ON
malloc 445k
AllocateMemory 1536k
stack space 529k
shoot_malloc contig 32M
shoot_malloc total 151M
Jayb, I think the files you are using from the post you are mentioning are from the 28th of august, it maybe that the build is very old. Try using a newer build:

Cheers. Have installed the latest version, no change – still getting around 140 frames. I can't seem to get the buffer from 151MB to 255MB unless I leave the cam set in
photo mode, as soon as I switch to
video mode I get 151MB again. If I record using photo mode (when it shows I have 255MB) I get less frames, around 122. Also very buggy and crashes a lot if I shoot in photo mode.
Make sure the memory hack is on in the advanced menu and photo quality is raw. You don't have to record in photo mode for that.
Also, FYI, with the memory hack the memory only gets taken when you start recording... as in you won't have it once it stops and it will go back to 155.
NOV3'rd is the latest I put up.

Thought it may be an issue with Mavericks (OSX 10.9) but it won't open in Mountain Lion either (OSX 10.8 )
It's the native unarchiver for mac, I used a different one I had and it worked fine. Download it from this link and you shouldn't have any more issues (it's only been unzipped then rezipped).

woop woop just got 2 new sandisk extreme plus (80mb read/ 60mb write)
getting 40.5mb WITH GD on and Canon preview = continuous at 1600x640 (2.50:1)
40.7mb without GD and hacked preview = 1140 frames at 1664x666, not worth the minimal gain with hacked preview
MUCH better results than my lexar pro 600x which i've paid more than double the price of the sandisk extreme plus
Ok, so, I'm stupid I guess, but what's the difference between hacked mode and non hacked? And how do I switch between?
This is a great thread guys btw.
