Title: 256gig 1200X KomputerBay CF cards.
Post by: ted ramasola on August 20, 2013, 09:00:19 PM
Their first batch got sold out already, but hopefully I will be able to test one by end of the week or early next week.
I'll keep you guys posted how it goes on the 5D mkII and 7D and hopefully a 5D mkIII.

How did KB send you that card? I was set up to be a tester for KB but never got notified. Did you?

So you actually spent $700. What a rip off of a price! It would be way more reasonable at $300-400

I'll see if it offers an improvement in continuous recording on higher resolutions on the mkII and hopefully on the 7D, if not I'll exchange them for a bunch of 64s.  :)

I won't be sure yet if it works across several models as we were not able to determine the firmware on the chips.

I wonder why they didn't make a 256gb 1050x card?  Seems like the price is rather high if you can get 2 x 128gb cards for $400 that'll roll continuous.

Unless (for some reason) you're shooting in 3.6k....

If the past is anything to go by bigger the card from KBay slower it will be with the exception of the 64GB that offers the same speed as the 32GB. Lets see what Ted reports finally.

I never reach the same speed in 60fps mode then I reach in normal speed.

Normal 100MB/s
Sqeezed mode: 80MB/s

Don't expect to get 1920 x 672/1080 60fps continously...

Tested on 5D mkII, mkIII and 7D.

The cards was tested to be compatible with magic lantern and canon firmware unlike the 1050x.

Benchmarks show similar results as 32 or 64 gig 1000x. The cameras seem to be the limiting factor.

When formatted as 256 gig via your computer or straight from the box, the cards will initially be seen as such by the camera.

However, when you format the card in-camera, it will reduce its capacity to 128gig.

Tested the 5dmkII for capacity test indicates it cannot record past 128gig on the card. (we recorded 116gig)

For now only 2 card readers are confirmed and tested to be compatible, the lexar and transcend card readers.
Other brands will only show the CF card as 132 gig only.

Pity... was hoping for better performance on the 5D3.  Did you happen to test the card write speed outside of magic lantern using something like CrystalDiskMark?

So, for 5D2, we have to wait for a 128GB 1200X with a compatible firmware ...  :-\

Hello Ted,

If I am understanding this correctly, is 1000X speeds about as good as we're ever going to get on the 5Dmk3?

It seems like there is absolutely no advantage to 1200X cards, and even 1050X don't seem to be performing any better.

Komputerbay is releasing 1050X 64gig cards in November:

http://www.amazon.com/KOMPUTERBAY-Professional-COMPACT-FLASH-Extreme/dp/B00DQ8WOW0/ref=sr_1_4?s=electronics&ie=UTF8&qid=1378623709&sr=1-4&keywords=64GB+1050X

Do you think these cards will provide any benefit whatsoever?

I ask because I think I want to buy a couple of additional CF cards (I already have 2 Komputerbay 64 1000X which I'm quite happy with) and I'm wondering if I should wait until November for the 1050X or if there's really no point based on your research.

Many thanks!

According to Canon themselves the maximum write speed of the Canon 5d mkIII is 167MB/sec.

This is the statement by Canon:
The DIGIC 5+ processor has also brought the ability to make use of UDMA 7 memory cards, enabling fast write speeds for both still images, where data is produced in bursts, and HD video, where continuous stream data is sent. This allows memory cards with a sustained write speed of up to 167MB/sec to be fully utilised, meaning the camera is future-proofed to be able to work with faster memory cards than are currently available in the market.

Canon also says that cf cards with the size of 256gb should work with the 5d mkIII, even larger than that would be possible.

Post by: Midphase on September 11, 2013, 08:04:44 PM
Regardless of what Canon literature says, this doesn't seem to be reflected in real-world tests. 1200X CF cards clock in higher than 100mb/sec write speeds with test apps when connected to a computer through a USB 3 CF reader, yet on the 5D3 they can't get anywhere close to that.

What is going on?

May I ask where have you read that the cards tested faster via separate test apps?  I've only seen screenshot results of those type of tests coming from Komputerbay themselves.  I had asked Ted Ramasola if he tested externally using a utility such as CrystalDiskMark but I didn't receive a response, so I'm still unsure if the camera is the limiting factor or the just that the cards themselves are not performing anywhere near their claimed write speed.

@MA Visuals,

oops, Sorry I wasn't able to reply to your question and request.
No I did not perform extensive tests outside the camera as the Card is very picky with card readers, more than the 128gigs. The 256 from KB at the time of testing was only compatible to transcend and lexar usb 3 CF readers. I did a limited testing with a friend who had the mkIII and a transcend reader but only to format the card, install ML and do benchmarks on his mkIII.

Upon realizing that the major cameras that use ML (mkII,mkIII, 7D) can't support more than the 128gig versions of KB cards, I was no longer interested in pursuing further testing.

Even when you format the 256 as 256gig, the camera can't record more than 128gig worth of data on it.

The moment you perform an in-camera format it reduces it to 128.

I saw no benefit using it so I sent it back already.

Thank you Ted.  For the price vs your tested performance, I would have returned it as well. 

That's actually very good news since it's no longer established that the camera is the limiting factor.  There is a possibility that the sustained write speed of the card you tested was just very similar to their other cards.

Here is the screen that shows the camera can "see" its a high capacity card. Its formatted in the PC.

Heres a benchmark done in camera with ML.

More test results I posted here: http://www.ramasolaproductions.com/6.html (http://www.ramasolaproductions.com/6.html)

Including resolutions on the 3 cameras tested.

I'd also add that I have been informed by KB that the higher end cameras, ie; 1D(xx,C) show a "different" result when using this card.
Perhaps they are compatible and can take advantage of the high capacity and speed.

Hello...

I am here just to be "updated". So, it looks like Canon says that if the CFcards evolve, than, more features and granted continuity will be granted in new versions of MagicLantern. Is that correct?

So, and to just make a point on the "correct" workflow, if the CFcards get to higher speeds, the resolutions will go up and that the 128GB card will be the 64GB card of nowadays. Correct?

In order to get a good workflow we need to dump this data somewhere to be able to work for 1 entire day with (virtually) no stops. So, is there any Portable device that can dump 128GB in say... 8minutes?

That way, with two cards, it would be great to work and no time lost. Could do a Documentary just to test this workflow!!

Thank you very much. Hope to get you oppinions on this!

The official canon firmware?  Video is limited to 29 minutes for a continuous video.

It was mentioned in the previous page that with ML firmware the card will only utilize 128GB of the 256GB card.. so I'd go with the 128s

Post by: arturochu on November 04, 2013, 07:36:03 AM
But if the new firmware reads the whole 256 gb, then maybe when ML updates to this firmware we could have longer raw record times and way faster cards.  ;)

Hey everyone - I'm new so please bear with me if I sound stupid lol. Just making sure I read this correctly - the 256G card will only hold 128G of footage in the 5D3? However, it will operate fast enough to actually record the raw footage - unlike KB's 128G cards? I've seen nothing but bad reviews on their 128G cards from what reading I've done on here.  I'm considering picking up a couple of their 64G cards simply because the price can't be beat and seems to perform ok?? Someone please correct me if I'm wrong.

Hi Ted,

Thank you for your time. Yes, I'm already familiar with your blog http://www.ramasolaproductions.com/6.html and your test with 256GB KB.

I have no additional questions regarding KB card, I still have 3 x 128GB 1000x KB cards that have failed multiple times and I have sent them back for 4 times by now due to several reasons (not quick enough, corrupted frames/artefacts, corruption of cards etc.). I don't trust these cards and that's why I'm planning to buy 256GB Sandisk UDMA7 160MB/s CF for my 5DmkIII.

This is why I asking about your experiment, cause I understand that you experienced this capacity issue (256GB card formatted in 5DmkII showing only 128GB of available space and even when formatted in PC, being able to store only 128GB of data) with only 5DmkII.

I cannot go with such an expensive investment via internet to risk with being able to use only 128GB out of 256GB. If this is the case I'm gonna go with 2x128GB Sandisk UMDA7 160MB/s CF cards. This is why I'm doing this pre-purchase research. The questions I have are:

1) 5DmkII and 5DmkIII cameras are different. Starting from firmware. Canon claimed that 5DmkIII is capable to record up to 256GB CF card when they release this camera. They didn't specify if photo or video. I tend to think that this rather goes to video cause photo is much less capacious. Also, Canon has released 2 newer versions of the firmware since the launch of 5DmkIII. None of these versions mention any capacity improvements under list of improvements. It's like there's no problem with that. Do we have a reason to suspect that one can't record 256GB/~48 minutes continues 1080p RAW video onto 256GB UDMA7 Sandisk 160MB/s CF card with 5DmkIII? I asked same question from our local Canon representative company, still waiting for the answer as they are discussing this with Canon international (or something like that). 

2) Is it possible that this capacity issue is something only Komputerbay 256GB card related (oh how I liked that)?

3) Most probably this has nothing to do with ML firmware, cause formatting goes together with Canon firmware, right?

Thanks again for your time. If anybody else have ideas, I'm one big ear...:)

Post by: ted ramasola on December 09, 2013, 03:36:00 PM
Sorry for the late reply Baarman,

The tests I did with the mkIII was limited.

The capacity issue is with canon cameras, KB informed me at the time I was doing the tests for the 256 gig that they stopped pushing it for other canon cameras except the 1DC. I don't know if it changed.

Anyhow, on my tests based on the KB cards available to me me for testing during that time, the most optimum performing card when it comes to speed was the 64gig 1000X. This is based on tests conducted on MkII, mkIII, and 7D.

it performed better or slightly better or near equal to, 1000X 128 gig, 1050X cards and the 1200X 256 gig.

Also. my personal opinion, due to the current experimental nature of magic lantern it would be prudent to use 64 gig than to lose a lot more footage on the bigger 128 or 256 card.

Like what kind of test for instance?

we know it can do 24P continuous around 10 minutes then we stopped recording due to lack of time and also since most practical takes in narratives and controlled set ups max out at those times.

For 30P it could only do 330 frames during the time we tested with the ML version available at that time.

Also continuous in 1920 x 1080 in crop mode.

As far as data rates, they did not show any improvement over the 1000X.

I saw no reason to pursue extensive tests when it could not be formatted in camera as 256gig.

The burning unanswered question for me is if you can fill it up with 256gb of data. In camera format is irrelevant for me, but to be able to store 47min of raw on one card would mean a whole lot for documentary and live event filming. If this works I would probably film everything in raw.
You might say that wold take a ton of space but with projects with a lot of raw material my plan is to develop the footage as the project progresses to DnxHD and throw away the raw files. A bit sad but a better compromise then filming those projects in H264 in my opinion.

I feel you, brother. :)
I bought 256GB Sandisk Extreme Pro 160MB/s and still waiting this to be shipped from CVP.Co.Uk. Hopefully reaches this week. I'll let you know about the compatibility with 5DmkIII. Canon told to me that it works, so I took the risk.

Btw, can't thank you enogh for this 5dmkIII vs zoom H6 favour, I'm using it and it's big deal. Hopefully ML dev will hear your raised request and we'll get the whole package! :)

:), Your welcome. I think there is a pretty good chance this could be tweeked for perfect start sync by delaying the signal to match video exactly.

Yep, I saw that you made it a day before yesterday. Cool, can´t wait to test it during the weekend. CVP just wrote that they handed over my Sandisk 256GB to TNT (it took them 2 weeks) and now it´s up to them when it gonna reach to me. Probably at the beginning of next week if it survives the Christmas traffic jam...

Hi,

Sandisk 256GB UDMA7 160MB/s (1067x) VPG65 card received and I ran a few tests: 

1) There's no capacity issue between 5DmkIII and this card. 5DmkIII shows the whole card and when you format it within the camera it makes it perfectly exFAT. Grateful for that.
2) I managed to fulfil the whole card with one .RAW file, did it multiple times with different resolutions formats,  frame and crop rates.
3) Recording speed didn't drop below 87MB/s (it depends on what format you use). If it started with 97MB/s it also ended with similar speed after ~48 minutes, so I may say that this card is extremely stable. Unfortunately it also didn't exceed 100MB/s write speed like a hoped a little bit. Tried that with recording some higher level cropped resolutions.
4) Everybody probably knows by now that this time/capacity related defect with buffer was fixed by ML recently and there's no issue with speed drop after 8-9 minutes of constant recording.
5) Camera temperature didn't raise above 68c through the whole recording process. It was lower at the very beginning and received 68c peak after about 13 minutes of recording. Then it stood around 60c - 68c rest of the time.   
6) Blackmagic disk speed test on Mac shows constant write speed ~124MB/s and read speed 132MB/s.
7) Successful continues recording formats without frame drops:

1920 x 1080 (16:9), 23,976fps, 24fps, 25fps.
1920 x  508 (2,35:1), 60fps

crop mode: 2240x954 (2,35:1), 23,976fps, 24fps, 25fps.
crop mode: 2048x872 (2,35:1), 60fps

8) Don't use Kingston FCR-HS3 USB3.0 UDMA7 card reader with this specific card, it doesn't properly support it. It won't allow you to copy all the recorded files from the card, neither write nor format the card. I'm now using Transcend TS-RDF8K (the one that was witness for several Komputerbay 128GB 1000x CF cards death. :) not sure what this was card reader fault or faulty KB cards or my iMac or Blackmagic disk speed test. Most probably the extremely unstable Komputerbay 1000x cards because one of them died in my camera once battery unexpectedly ran empty).

This Sandisk 256GB card deserves a new topic, I'll start it as soon as I have a moment.

Happy upcoming X-mas for everybody!

Nice to hear the sandisk card works well on the mark iii, you didn't mention 1080 30fps, i'm guessing its not possible. Hope someone could update the test of the KB 256 in the mark iii, that card its way cheaper than the sandisk one, and in theory its way faster.

Hi,

arturochu, you are right, 1080p 30fps was only for some limited time (under minute or so). Where do you need to use 30fps 1080p? AFAIK not cinema/TV compatible anywhere nor enough for downscaling to get slow motion...

Hi everyone, I got a 256GB card and just did a first trial on the 5dmkIII.  Formatted it EXFAT with a Transcend USB 3.0 card reader.  Did a continuous recording test at 1080p24.  I got about 26 mins continuous before it automatically stopped.  I re-started the recording and it filled up the rest of the card.  Haven't reviewed the footage for bad frames, but it appears stable at 24p at least.

hey rungunshoot, can you extend your review about the 256 gb card?

*what brand?
*24, 30, 48, 60 maximum res for continious shooting?
*format in camera formats the whole card?

cheers!

Brand was Komputerbay 1200x...sorry, thought that was assumed in this thread.

I only tried 24p @ 1920x1080.  I have yet to post process the files, so I don't know if I got any pink/bad frames.  But I was able to fill up the card with only one re-start of the recording button (around the 26 minute mark).

I formatted EXFAT via Macbook Pro.  Transcend USB 3.0 card reader.  The in-camera formatting reduces visible capacity to 128gb.

Once I'm confident in the 24p recording I will attempt higher framerates/resolutions.

I just realized something...

The 5dmkIII is supposed to sense the card's capacity and format EXFAT internally to use the entire capacity.  It didn't do that for me - formatted as 128GB instead, presumably Fat32.  Any ideas why?

Post by: arturochu on December 24, 2013, 01:34:24 AM
not sure why, tamasola also had the same problem, but just to clarify, if you format exfat from computer the whole 256 gb appears in camera? hope you can test with other than 24p so we can know how fast is this camera in practice. Thnx anyway.

Yes, 256gb appears in-camera if I format from computer...well, actually 238GB or something.  Whatever the card actually holds.

I did a few more quick tests:

- approx 146GB seems to be a stopping point for continuous 24p recording. Not sure why. Slow spot on the card?  I have emailed Komputerbay for tech support on this.

- Recording at 48p (FPS Override), I'm getting about 6 seconds at 1920x672, 8 seconds at 1856x650, 1:30 to 2:00 at 1728x606, and continuous recording at 1600x560.  Global draw off.
