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?

Same here... I had received 2 64gb Komputerbay 1000x cards this week and only 1 worked in my 5d3. The other worked only on the pc but not in the 5d3. Returning that one and getting a replacement. Has already returned the 128gb due to slow write speeds. These cards are hit and miss. The good 64gb card however is pretty fast and 1080p works well.

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?

Even when tethered it says "unable to use card". I did a full low level format, same thing. Now doing a full exFAT format in Windows 7 64. Not looking good.

Did you buy them on Amazon or ebay?

I can confirm the slow 128GB cards.

Sending it back right now, getting a 64GB card instead.

My KomputerBay 64Gb 1000x card is slow? I´m getting in Mode(Movie) 64.6 MB/s writing speed (Buffer=16384k) I´m filming on a 5DMk2 at 1880x720 without frame skipping until it reaches 4Gb, then stop.

I purchased 4 KomputerBay 1000x 128 Gig cards thru Amazon, non of them could deliver 1920 x1080 on my 2 5D Mark 3's I've returned them all for a refund... top writing was 66 or 67 MB/s from one of them the rest were low 60's.

soundsubs · « **Reply #32 on:** May 28, 2013, 10:33:51 PM »

I guess i'm lucky, because I got a 64gb Komputerbay card (from ebay) and its working great in all modes.

I ordered 6 128GB 1000x Komputerbay cards to pick out the fastest of the lot. All of them were pretty similar hovering around 71MB/s. Fastest one topped out a little over 75MB/s. My 64GB 1000x Lexar absolutely blows it out of the water hovering around 95 MB/s. I ordered a 128GB 1000x Transcend card so I'll report back with the results. Right now it looks like the 64GB cards are the way to go. I like to use the 128GB cards to edit off of with my USB 3 card reader. Saves space that I don't have to use with my Macbook Pro Retina or external.

Well, as I mentioned in another thread - I've ordered 3 Komputerbay 64GB cards and so far only one has been "as advertised" speed-wise.
Card 1 - Computer could see it, card could not be read by computer. After several attempts too.
Card 2 - Topped out at about 67 MB/s
Card 3 - very nice with consistent results. Even a tad faster than my Lexar 32GB 1000x card.

As a point of reference, here's the other 64MB 1000x card (which shall be returned):

I just got my Komputerbay 64 GB and I figured I might as well post my benchmarks as well.

I'm pretty disappointed, I can only record 1920 x 1080 for about 135 frames until I get frame skipping.

I got it on eBay if it makes a difference.

I'm considering returning the card. Any suggestions on whether I should grab another Komputerbay or opt for a Lexar 1000x? Or perhaps another alternative?

Why would you send that card back? My 64GB 1000x Lexar is slower than what you posted. That should be plenty of speed to shoot continuous 1920 x 1080. I have no issues at 1920 x 1080 with my slower performing card so I'm not sure what's going on with yours.

Interesting, I'm not quite sure how the W/R speed compared to the performance of other cards, but I guess I was disappointed that I'm not able to shoot continuous 1920x1080. I'm not sure what I'm doing wrong, I have GlobalDraw turned off and I've been trying to find the optimal settings, but after about 135 frames, there's just a crazy amount of frame skipping. There are instances where I get frame skips right when I start recording, at frame 36 or some, and it just gets worse after that.

EDIT: Well I figured that out pretty quickly. I knew I was missing something, and I forgot to turn on the FPS optimization for 24 fps. I successfully recorded without any frame skips, thanks for pushing me in the right direction Jason!

Seems like the SM2236AB cards are slower than the SM2236AC.

Kraemer · « **Reply #40 on:** June 05, 2013, 08:18:10 AM »

@ Khoi

I can confirm a slower komputer bay 64 card; and I too can only record about 128 frames before skipping sets in. (on the 5D3 at 1920x1080)

My write times (on the same CF benchmark test from the May 28th build) are: ( I left out the READ speeds / dont know how to post the above pic)

Got mine at amazon --SHOULD I exchange it?

WRITE:

67.2 (buffer=2040k)
57.5
71.0
61.0
70.9
67.4
74.6
74.1 (buffer=15625k)
28.3 (buffer= 128k)

Did anyone test a Toshiba 1066x?

sebamax · « **Reply #42 on:** June 07, 2013, 09:28:08 PM »

today i tried a komputerbay 64GB 1000X (X0005E2NNV)
on 5D MarkIII formatted exfat
1920-1088 it records continuously, no skipping frames (global draw on)
Crop 3X gives no problems (it records continuously)
60 fps 1340-470 it records continuously

It Works similar like a Lexar 1000X 32GB (I still got it)

Where did you purchase? Also, are you in the United States?

Mei Lewis · « **Reply #44 on:** June 11, 2013, 01:25:42 PM »

Just got a64gb from Amazon in the UK, trying to figure out if it's fast enough.

These are probably silly questions, but I can't find the answers anywhere

1) How do I get the benchmark info from my camera screen onto this forum? Is there a way to take a screenshot to a file somehow?

2) What write speed is the minimum for 1920x1080? Ideally in 25fps? The ML menus say 86.4 I think, but people are reporting being able to record continuously even with write speeds that dip below that.

a1ex · « **Reply #45 on:** June 11, 2013, 01:44:23 PM »

The speed from ML menu is accurate for continuous recording.

odlan · « **Reply #46 on:** June 12, 2013, 12:10:50 AM »

I confirm very poor performance on Komputerbay 128Gb new and format in exfat

max write speed around 70 Mb/s no 1920x1080 raw recording is possible

No problems with Lexar 32 Gb exfat

thhmo · « **Reply #47 on:** June 12, 2013, 08:47:33 PM »

It seems that I'm lucky with my komputerbay 64GB 1000x!
I'm getting max write speed at 121.4 MB/s at 16384K buffer and 114.8 MB/s at 3072k buffer.
I don't know how to insert the "vram.bmp" from the camera.

Kraemer · « **Reply #48 on:** June 13, 2013, 05:16:00 AM »

Yea me too

My 1st.) first Komputer bay 64Gb card was not fast enough for more than 129 frames of 1920x1080,
now the replacement for that card(#2) has got serious issues. it worked at first, but now the card is crashed.
It won't let the camera boot and it wont be seen by the computer via card reader. (mac)

Hey Ya'll

Here are my benchmarks on 1000x Komputerbay Cards in 32gb, 64gb, and 128gb

32GB

64GB

128GB

How are these stacking up? Should I replace the 128 with two 64's?
I still need to read on workflow as I could only get 1920x1080 @ 24 for 100ish frames. Not to mention I couldn't find the damn dngs
