There is some kind of inconsistency with these cards. Alot of people buy these cards but keeps getting different results.

Post your size,highest resolutions and benchmarks test.

I got a 32GB card.

I got do 1920x1152 24fps without a sweat.

Speed varies by capacity size, so this isn't a new phenomenon.

16 GB cards are usually slower than higher capacity cards, depending on how many NAND flash dies they have in parallel to the controller.

I read that a member here had the 64gb cards that he sent back after a couple of days because they died on him.

Has anyone on the boards had a 64gb card that could NOT record 1920x1080 without drop frames for 4gigs?
Also, has anyone here had the 64gb cards longer than a month without them dying?

I've read a few reviews on these cards from ppl who have had them for a long time without issue, but I'm sure that they weren't shooting raw video. I'd like to know if these can stand the test of time while shooting this 1080p raw

My experience with the 64GB Komputerbay 1000x card has been pretty good. Can record 1920x1080 no problem..On the may 13th build it could keep up 1920x1152 but on May 18th/19th build it can't. But yeah here it is

Hi, i am on my tablet and can't send you the report of my card testing, but i can confirm that my Komputerbay 64GB 1000x, which just arrived today, works perfectly in RAW video usage. I did a benchmark, top writing speed at 128MB/s

My 64GB 1000x has just arrived, initial test not looking great. Wouldn't allow 1920 x 1080 and only managed 150 odd frames at 1880 x 1080 using May 19 build on 5d2. Global draw off, no sound.

The 5d2 cannot do 1920x1080, according to developers, they cannot extract 1920 from the sensor only 1880 x1080.

>only 1880 x1080

Confirmed perpetual res for 5d2 on fast cards? That'd be close enough to HD. I can only get up to 1880x720  on my Sandisk Extreme.

Never mind, I need to learn to read. Still interested in max perpetual res on 5D2 on fastest cards. Should we hope for full HD, or give up the thought?

Thanks, Ted.

Seems the highest reliable resolution is 1880 x 840 for me, which is certainly usable.

1880x840 is great but if you need to fill a standard HD frame, try 1720x960.  When blown up to 1920x1080 it still looks worlds better than H264.  I'm getting about 450-600 frames at this resolution on the 5D2, at a write speed of about 59MB/sec on a Lexar 1000x 32GB.  An improvement to 64-65MB/sec would probably enable unlimited recording at this resolution.  I'm optimistic that Hack3d mode or other write speed improvements will get us there.  Is anyone seeing reliable 65MB/sec speeds on any Komputerbay cards?

My 128gb 1000x averages at around 67mb/s. Disappointed! With the new build I'm only able to record about 120 frames.

Returning for a 64...

20 May build, 5d2, 1720x960, Lens cap on, GD off, sound off, hacked off:

1st clip: Buffer had just reached 4 stars, then I reached the 4GB file limit, so not perpetual recording at that resolution for the 64GB Komputerbay in a 5d2.

2nd clip: 1242 frames then dropped one, buffer filled quicker this time.

3rd clip: Buffer coasting at 3 stars at limit.

4th clip: 5 stars flashing at limit.

5th clip: 3 stars flashing at limit.

67MB/s was the peak speed, but averaged 65.8MB/s to 66.2MB/s.

Will do more tests with hacked and complex images



1880x840 is perfect for 2.35:1 just needs scaling to 102.1%

Wow, impressive!  That's with the 64GB Komputerbay 1000x?  Not sure why I'm not getting these speeds with the Lexar 1000x, but it may be time to pick up a Komputerbay.

Yeah 64GB 1000x Komputerbay bought from:

http://www.amazon.co.uk/gp/browse.html?ie=UTF8&marketplaceID=A1F83G8C2ARO7P&me=A15KH8GEK4WQL1

I was thinking of getting a 32GB Lexar, but if this is faster as you say then I'll just grab more of these.

Toshiba 1066x claims to have 150Mb\s write speed, Transcend 1000x also might be worth checking as it should be capable of ~120Mb/s

As I understand it from elsewhere on the forum, Komputerbay is just a supplier to Lexar and the cards are otherwise identical.  So I don't know what accounts for the difference in write speeds.  But if you're already getting A-list write speeds, then if it ain't broke, don't fix it!

The Transcend 32GB 1000x can be picked up for just under the same price as a Komputerbay 64GB 1000x. Would need to see a drastic increase in card speed to justify that, although we will see how these cheap cards hold up in a month's time.

I saw the post regarding the origins of the cards. The Amazon storefront is registered to the area mentioned in it, so it seems legit.

I was going to buy a couple of the 64gb cards. People seem to say they are fast enough. BUT, there are others who claim that the cards are DYING. I did a  google search for konputerbay(not the specific cf cards) and they also sell ram. MANY people have complaints of the ram just dying out. Anyone been using these cards longer than a month?

I think with these cards it's the luck of the draw. The chips could have failed Lexar's QC for different reasons, some of those reasons will be minor and some more severe. I think I'll hold off on new cards and see how the ssd route pans out.

Just got in a 64GB Komputerbay 1000x card.  Works fine in a PC but the 5d3 cannot see or format the card.  Doing a low level format now and going to re-format with exFat (windows shows it already WAS exFat).  Anyone have this problem?

Mine worked fine straight out of the box. All I can offer is maybe install the card in the camera and tether it to the pc?
