Title: Komputerbay 1000x Cards - Benchmarks & Uncompressed video resolution
Post by: Vegandelight on May 19, 2013, 04:31:13 PM
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.

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.

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.

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.

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.

Komputerbay 64GB card:

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!

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?

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.

The speed from ML menu is accurate for continuous recording.

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.

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)

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.

Hey Ya'll

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


32GB

64GB

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

Hi.

Maybe if everyone tests under the same conditions you'll get a better idea of how your card is performing. Many members appear to be testing in different camera modes, which from my own tests gives largely varying results.

It seems there are many other things can can influence the test results too.

Check what "Mode" your tests are being performed under, it makes a big difference to your results. The mode shows up in the top part of the benchmark image/display.

(https://www.magiclantern.fm/forum/proxy.php?request=http%3A%2F%2Fi.imgur.com%2FLJhHc0T.jpg&hash=5fc41ebb47e9e2b88a233655a0eb71bd)

Some have been doing tests in photo mode which tends to yield faster results than "movie" mode. To get the benchmark to show "photo" mode;

1. In camera mode (not video), press the info button so that your display shows the "shooting info" display similar the following image (these are not my exact test settings - just ensure that this settings preview is showing)

(https://www.magiclantern.fm/forum/proxy.php?request=http%3A%2F%2Fi.imgur.com%2FYNrw9py.jpg&hash=36322ee2181650904b3b157bfa578652)

2. Turn off "global draw"

3. Do the "Benchmark read / write 5min test" immediately after formatting the card in the camera.

These are one of my results with the Komputerbay 64gb 1000x card while in "photo" mode.

Kraemer,

The screenshot is grabbed from the card - it's saved in the root dir as "VROM.bmp" or something like that...


I'll retest my cards again later but I'm wondering if I should replace the 128gb with two 64gb's.

Your 128GB results are invalid as you ran the benchmark in playback mode. Run it in movie mode with live view enabled to get an accurate impression of how it will perform during raw recording. You will find it is slow - around 70MB/s, pretty much all the 128GB KomputerBay cards are. The 64GB cards are fastest.

Hi everyone. Very excited to be trying ML on my 5d III! I've got a question regarding the benchmarking and I'd greatly appreciate if anyone can help.

I've bought 5 Komputerbay 1000x 64gb cards and I've been doing lots of benchmark tests.
 
One was DOA. The results with the others I'm getting aren't too great to be honest. The best performance from one of the cards at buffer=16384k was 88 MB/s.
 
The tests were conducted in movie mode, 1920x1080 25p, global draw on (Focus peak).

I then tested my Lexar 1000x 16gb card was quite interesting. Read was in the 700s but Write peaked at 12 MB/s
 
Am I performing the tests correctly?

Just out of curiosity I left my KB cards recording 1920 16:9 25p and the buffer didn't max out for any them. Is this a good enough though?

Hello everyone,
I am new to the whole  ML Canon business and tried to shoot raw today the first time using the Komputerbay 64gb 1000x cf cards (new). Initially, it worked but after formatting them a second time (with mac to exfat), one card became completely undetectable and the other one last half its benchmark performance. formatting it again, made it even worse.Now this one is also completely useless.
 Could anyone help? I am totally frustrated and couldn't find any answers online so far. Thx, Tobi

are you using USB 2.0 card reader? If so you could have corrupted your card. You have to use USB 3.0 slot and reader for these CF cards.

I was talking with KB techsupport about this and after installing a usb 3.0 addon card and reader I don't have corruption anymore.

You'll know its your reader when your camera and your computer can no longer format your card.

what about using usb3.0 CF card reader with the old laptop with only 2.0? Will this corrupt the card?

Post by: Midphase on July 31, 2013, 10:58:10 PM
I really haven't had any problems whatsoever formatting my CF cards to ExFAT using a USB 2.0 interface.

All in all I must have lucked out because both of my Komputerbay 1000X 64gig cards can handle 1920X1280 at 24p on my 5D3 without any issues. One of the cards sometimes needs to be warmed up a bit, and it helps if I turn off GD when shooting with it, but otherwise I'm a pretty happy camper!

Hi I have been having some real issues getting RAW to work and only just succeeded by putting my FPS down to 25 from 30. Now I get continuous RAW recording. This in on a Canon 50D btw. So I see the 50D can only do around 70mb/s I guess this is the problem?

My benchmark ALWAYS crashes in movie mode so I had to take a photo:

But it playback it goes up to over 100mb/s?
I am confused.

Hello.
I´ve got the latest build (2013/09/20) installed and got a new Komputerbay 64GB 1000x card on my 5D2.
Here is the benchmark:
(https://www.magiclantern.fm/forum/proxy.php?request=http%3A%2F%2Foi39.tinypic.com%2F1jnrdz.jpg&hash=41878617a3c232473df378a3775a511a)
Not very exhilarating ...
(Why is there no chipset on it? Is this feature just for the 5D3?)

With 1880x1058 (24fps) i can get around 75MB/s with 1300 frames.
With 1728x972 (24fps) i can get around 75MB/s, at first it says "continuous" but than writing speeds are getting lower each second. (75.0MB/s ... 74.9MB/s ... 74.8MB/s ... ... even to 10MB/s)
Is this OK? Or should i send it back?

If I plug it with my Komputerbay 64gb 1000x to an usb 2.0 port, will it be corrupted or collapsed?

There's been reports of people who has fried their cf cards by plugging them to usb2.0 card readers, but I haven't found reports regarding the setup I'm suggesting.

According to the email conversation I just had with KomputerBay, that combination should be fine since it's the reader that causes the problems rather than the USB port. I posted more details here: http://www.magiclantern.fm/forum/index.php?topic=6884.msg88538#msg88538

91Mb is great, better than ok. You really only need 80-something Mb/sec anyway so you have room to spare.

1728X1156 is the maximum non-Crop mode resolution that the 7D provides, card has nothing to do with it.

I don't see why I should perform it in playback mode? When recording raw movies in 16:9 the movie stops after 5 seconds. So I guess that is not a good card with such short record times. Other users posted  movie-mode results with double the speed that I have with my card.

But to be sure I made the test again in playback mode.

Write: 71.7 MB/s
Read 91.2 MB/s

FWIW, I have CF cards that can record continuous 1920x1290 on my 5D3, and can't  handle more than a few seconds of 16x9 on the 5D2 (but can go continuous at 2.35:1).

Based on my experience, it's not the cards but the write speed on the 5D2.

P.S.

Same CF cards can handle continuous at 16x9 on a 7D.

Well, I have a friend that has the same Komputerbay card and can record for over a minute in 16:9. On the web there are others that can record a lot longer than a minute, so I think the slowness of my card isn't meant to be.

I will send it back and hope that the next one is faster or I will invest in the Transcend 32gb 1000x. Never had any issues with Transcend, what do you think?  :)

Today I recieved my 128 GB 1000x and of course I want to test it. I could record 1920x1080 until 4 GB are consumed, then it ends. How can I start this speed test? I searched in all menus and didn't find anything. I have 5D3 with ML from Aug13.
Because today I read, that my old card reader could damage the card, I first have to order a new UDMA7 compatible one before I can transfer anything to the Mac.

Okay, I found it under Debug/Benchmarks.

But it breaks within the 2nd read pass.
I chose "Card R/W benchmark (5 min)"
It shows: Blocksize 2048 73 MB/s write, read 100 MB/s
Blocksize 1953 53 MB/s write and read fails after 31/100 loops.
Is that normal? What does it indicate?
Could I set the blocksize to improve speed?

Disable Auto power off.  If may be shutting off the cam before the test finishes

Also check to see if you have the correct optimum settings for RAW recording

VERY IMPORTANT make sure that in Canon Menu:

Image Quality = Raw  for 5D3, 650D, 7D
 Image Quality = jpeg for 60D
Auto Lighting Optimizer = OFF
Long exp. noise reduction = OFF
High ISO speed NR = OFF
Highlight tone priority = OFF

Toshiba 1066x claims to have 150Mb\s write speed, Transcend 1000x also might be worth checking as it should be capable of ~120Mb/s
Toshiba is the second largest producer of flash cards after SanDisk so it doesn't sound unreasonable. They have also developed the worlds fastest SD cards with write speeds over 250 MB/s (too bad Canon's SD slot is limited to 20MB/s).

This is one case where the speed of the card is greatly superior to any device capable of supporting it. Lets  just hope Canon gets the memo come the release of 5D Mk IV.

A couple of questions about benchmarking.

How can I be sure that ML is benching marking the CF card and not the SD card?

How do I stop a benchmark test? How do I know when the 5 minute test is up? It doesn't seem to stop automatically.

Is it possible to have the write speed appear while one is recording .MLV or ML RAW?

Appear in the top of the screen. 89..92...
Try to rec .RAW or MLV, if works, forget the test.
Your card should work fine.

Ps.: in the sd card you can't get more than seconds. Or nothing and stop recording. Select CF card!

Thanks for your reply. I don't understand the benchmark because it says my speeds are between 12 - 20 MB/sec but I am able to record .MLV so I am going to take your advise and forget the test.

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

I 've bought trascendent 32gb 1000x but am not able to record full hd without crop ,as well on the lexar x 1000 and the komputerbay  x 1000.

So the only chance are the new toshiba 1066x or komputerbay x1050  but who knows if  the can handle with canon 5d mr3 full hd 30 p continuous?!on paper they say yes..?!

anybody tried one of those...?

It is just matter to have the right CF that writes above 100 mbs if we could use SSd there were no problems for of buffering,stopping, missing frame..etc

Hopefully there 're going to be in the near future CF cards that writes 120 mbs for real...but not for now

ComputerBay x1000 64Gb it's enough. Works perfect!

These are the benchmark results for my KOMPUTERBAY 64GB CF CARD 1000X in the Canon 50D.

I'm currently selling two of these cards on the dutch website Marktplaats: http://www.marktplaats.nl/a/audio-tv-en-foto/fotografie-geheugenkaarten/m811324129-super-snelle-komputerbay-64gb-cf-card-1000x-voor-raw-video.html.
So if you live in the Netherlands (or close by) and need fast shipping you should have a look at my offer :)

Hi

My first post here. Here are the results of my two recently purchased Komputerbay 64GB 1000x cards. Do they seem OK?
At least the cards record 1080x1920 25 fps RAW just fine.

Despite searching, I did not find proper explanation/manual of the benchmarks. Is there one? A link would be appreciated.
Thanks!

P.S How can you export the benchmark as a picture like above?

Recently got a pair of Komputer Bay 1000x 64gig cards and have been running benchmark tests.

Now Komputer Bay says in the specs these cards should be getting a minimum of 140mb/s WRITE speed. I seem to be getting half of that. Is this normal with ML? Should I send them back and try again?

Not really, cards are always rating for READ speed and not write speed. However, what you see are the hardware limitation in the camera body.

Actually the specs on the website are "KOMPUTERBAY 64GB COMPACT FLASH CARD CF professional 1000X 140 MB/s WRITE and 155MB/s READ speed RAW Extreme 64 GB UDMA 7"

So why is no one getting close to that 140MB/s? A few people at least are getting into the triple digits. Mine are stuck in the 80's...

If you think it's the camera, check out the benchmark tests I did on my computer via a new card reader. It actually did a lot worse (on the left is my card, on the right is the website selling the cards with a "screenshot" of how they are supposed to perform. I used the same testing software.

Here is the second card, also performing much worse.

Could be counterfeit products.

Could be counterfeit products.

Word is they are Lexar cards that failed quality control for a variety of reasons. So it's bound to be hit and miss....

I just ordered two more and will compare when they arrive next week.

---

Update, two new 1000x Komputer Bay cards have arrived, and I'm afraid they benchmarked even worse than the first two, never getting write speeds above the 50's, though the company claims write speeds of 140 minimum.

I will be returning them. Thank goodness Amazon makes it easy.
