Supported 1000x CF cards for continuous RAW recording

[ted ramasola]

I am talking with Komputerbay techsupport right now to isolate this problem. For now for those with UDMA7 1050x cards have a problem with older non UDMA7 card readers. If you have this hold on for my updates and DO NOT plug it into older cf card reader as it WILL CAUSE CORRUPTION ON THE CARD.

I'll update this post in a few hours as tech support will also be calling those who emailed and contacted them so we can isolate the problem.

[ted ramasola]

One of the issues in using the new 1050x cf cards is using non UDMA7 card readers,

According to Chet at techsupport, non UDMA7 has the potential to corrupt the new 1050x cards. His advise to those who have purchased this fast cf cards is DO NOT INSERT THEM TO USB 2.0 CARD READERS.

UDMA7 card readers for USB 3.0 should be used as the new cards use a different voltage. The cards would protect itself and give you "card is write protected" message when an incompatible card reader with a different chipset is used. This will prevent further damage to the CF card.

They are sending over 2 128gig CF cards which I will test for the mkII, one is a new 1000X from a new manufacturing batch which they said has no more issues as the early ones and another 1050x CF which hopefully I can get to work with a compatible CF card reader.

I will update this when my tests will be done.

So far, one thing goes well for komputerbay for me, and that is a great and responsive technical support BASED IN THE U.S. that will resolve the issues you have with their product. Stay tuned.

Since when did you buy the 5D3? Much better than the 6D in terms of raw video...

Yeah, bought 5d3 couple days ago.
I am waiting for komputerbay 64GB but today bought sandisk 600x udma7 32gb, it's beyond my expectations, i am really impressed  And it's sandisk so i hope it will be quite reliable.

for 24fps
2048x856 (2,39:1) continous OK
2240x938               continous OK
2560x1072            350  frames  - as a 6D user i get used to such a frame number so very usable 
2880x1206            120 frames

6D (with the VAF filter) raw 1808x756 (upscaled to 1920x800)  vs 5D3 raw native 1920x800 - really hard to see the difference IMO (5D3 is continous of course but I didn't record clips longer than 20 sec).

Well congratulations buddy hope your happy with the camera.

Today i recieved Komputerbay 64GB 1000x, works like a charm 
2560x1090 (2,35:1) gives ~500 frames, 2560x1072 ~600 frames.
Seems that even 2,5K can be very usable.

[a1ex]

Just tried mine (Komputerbay 32GB 1000x): at 2560x1090 23.976 it records around 1000 frames (estimates 1500). Will try to fix that (the buffering algorithm should really get 1500 frames, but it's stopping early).

Writing speed is around 109.5 MB/s (minor drop at the 4GB barrier). With exfat there should be no drop.

At 2560x1280 I get around 200 frames (both real and estimated).

Settings: 23.976, global draw on, no overlays enabled, all hacks from raw submenu enabled.

[kgv5]

Seems it is faster,  I am getting ~102-103MB and 500 frames is the 2560x1090 max

[xNiNELiVES]

So the 64gb is slower than the 32gb? Or did you get a slow copy of the 64gb?

[kgv5]

Don't know yet, it is super fast for me, couple days ago I had 40 with SD card 

EDIT: seems it is a slower one, in 5min benchmark max is 80 something but i am getting ~1000frames 1920x1080 30p, 24 and 25 continous of course. In fact not much faster than sandisk 600x udma7 32GB.

Compare your 64GB to other KB 64GBs. You probably got a slow copy, I've always heard that the 64GB are just as fast as the 32GB.

In fact i did, it is not even achieving 90MB/s (82-88MB/s) in 5min benchmark, many people had 100-120MB.
But...for 1080p 24 and 25 is continous, 30p gives about 700 frames, quite enough for me, it is not bad. I think i will keep  it, i don't want to wait couple of weeks and than get the one with 70MB or so. For the price -i think it is ok, the more important is how reliable it will be.

Yeah. The pitiful thing is that you're getting exactly what my 5D2 gets with that card, except that I have a 32GB 1000x.

In fact, no, I just got 90MB/s.

Just got the Transcend 64GB x1000 UDMA 7 which I bought form B&H - works perfectly with no dropped frames on my 5D3, 1920x1080, 25p.
I also use the Lexar 32 GB x1000 UDMA 7 which doesn't perform as well as I get a few dropped frames until it warms up a bit and then it's OK.
EDIT: See my next comment below.

[oferlevy]

Hi all,
I am trying to record 1920x1080 25p with my new Transcend 64 GB x1000, UDMA 7 which worked like a charm yesterday and it doesn't even do more than 3 seconds on my 5D3...
I haven't chnaged the settings and the Lexar x1000 32 GB works perfectly!
I have ordered the Transcend 128 GB x1000 UDMA 7 but maybe I should cancel my order??
Help please!

[kgv5]

Are you sure your camera didn't switch to sd card recording?

[oferlevy]

Are you sure your camera didn't switch to sd card recording?

Yes as I was trying the Laxer 32GB x1000 before and after I used the Transcend and it worked fine. The strange thing is that yesterday the Transcend worked like a dream - is it possible that it was somehow corrupted? Maybe by the card reader?

[ted ramasola]

did you try to format it using your camera?

what is your USB card reader? usb 2.0 or 3.0 ? some 2.0 cf reader will corrupt udma7 cards.

[oferlevy]

Thanks guys!
I have managed to get it back to life by formatting it with the Transcend Autoformat which I downloaded from their website. I chose the 'complete' format as the 'optimised' didn't seem to do the trick. However, I think I am going to return this card and get another Lexar 64 GB x1000 UDMA 7 as the Lexar 32 GB works well.

[soulshooter]

can anybody confirm if the transcend 1000x cards play well with continuous raw? 32/64/128GB?

the komputerbay cards seem to be hit or miss and lexar seems to think it's selling diamonds...

[ted ramasola]

Soulshooter,

I can't comment on the Transcend as the ones I have are older slow speed ones.

But with regards to KompmuterBay CF cards which I have been using and also testing several CF cards for ML use I can tell you the
KB 32gig and 64gig 1000x are at par with the Lexars which I also have. 
I have been testing for the past weeks several CF cards from  Komputerbay tech support themselves which know the specific needs of Magic Lantern users.
I'm testing CF cards that are not even sold like the 800x, I'm testing to see if its usable with ML raw video, unfortunately the 800x is not fast enough. We're still figuring out which controller firmware for the 128gig cards will make them work on the mkII, we know they work on the mkIII but KomputerBays also want to solve compatibility issues of the 128 gig on the mkII and 7D cameras. By next week my test on the 128 will be concluded so we'll know.

The 32 and 64gig 1000x, are good. Just make sure you use udma7 usb 3.0 cf card readers.
If ever they fail, komputerBay will replace them or refund you.

[ted ramasola]

Here's the test results I did on the KomputerBay 128gig 1000X CF.

The 128gig 1000X KomputerBay cards to work both on 5DmkII and 7D. The 128 gig 1050x WILL NOT.

This is due to firmware on the CF controller, its older than the one on the 1050X. But both controllers are the same.

The 128 gig is slightly slower than the 64 and 32 gig version and here is a comparison of resolutions and number of frames the 128 can do on the 5DmkII.

Raw video recorded frames on 5DmkII (compared to 64gig in red)
1880 x 1058 16:9    = 762     ( 1049 )
1880 x 940   2:1     = 14,641    ( continuous 21,763 )
1880 x 800   2.35:1 = 17,875   ( continuous 21,763 )
--
1872 x 1054 16:9    = 686   ( 1,429 )
1872 x 850   2.20:1   = 16,777   ( continuous 21,763 )
1872 x 748   2.50:1   = Continuous
--
1856 x 1044 16:9    = 702   ( 1,960 )
1856 x 790   2.35:1   = 19,192    approx 50 GB 
1856 x 742   2.50:1   = 43,156   approx 100 GB
--
1728 x 972   16:9   =15,578   ( continuous 21,763 )

Good tests. Hope KB sees this with their account.

[ted ramasola]

KB already knows these results. They have provided me with assistance on the tests I have been doing.
By end of the week I will be testing their new 256gig 1200X CF card to see if they work with the 5dmkII and 7D. I might also be able to test it with a mkIII.

What I like is that they are following magic lantern developments and are trying to see which firmware will work with most canon cameras.

There are trade offs so a decision will have to be made on their part.

For instance, older firmware allows their high capacity cf cards to be compatible with mkII and older models.
However, this makes the cards susceptible to software or hardware corruption when used with older usb 2.0 cf readers.

New firmware adds better protection to the cards making the older cf readers "not detect" or see the CF cards thereby protecting it from being shorted or corrupted
however this makes them incompatible with several canon models.

256GB 1200x, Jesus christ man.

Wouldn't it be possible to flash a custom firmware developed my magic lantern to fix this?

I mean I rather use the old firmware because I have USB 3.0, I thought the older firmware has slower CF r/w speeds and is incompatible with ML. Is this true?

[ted ramasola]

I was not able to compare speeds between old and new firmaware as the 128 gig with new firmware would not run ML.
However, if I based it against the 64 and 32 gig which practically has the same controllers, I'd say the older firmware running on the 128 gig is a tad slower.

So for instance on for 1880 x 1058 16:9    the 128 gig gives 762  on the 64 its 1049.

at 1728 x 972   16:9 the 128 records 15,578   frames which is continuous 21,763 frames on the 64. But hey, thats already more than 10 minutes of recording.
