Which Compact Flash card for 5D Mark III raw video?

Recommended Posts

I see few discussion threads around the web for hacking a connector from the pins inside the camera (cf pins) into a SSD or HHD. People seem to be confused in one thing and thinking that they could use regular IDE-harddrives. Where as in reality a IDE-harddrive is not even 80MB/s in consistent writing speed.  I would only Tinker with a proper SSD like Samsung 830, 840 , Crucial M4, M500 series. The power draw of the SSD might a choosing factor as well.

 

And when I had made up my mind about it..

Komputerbay 1000x 64GB CF cards are out from Amazon.de.

I'm starting with a KomputerBay 128GB 1000x CF card.  At, say, 1280x720 I wonder if the pattern in the poor performance is a sign I'm missing something in the setup -- exactly every 37 frames acquired it drops a frame.  I'd think there'd be a little statistical variation around that -- so I'd appreciate any tips, including 'the obvious' for things besides a lousy card that might be causing that.

 

Thanks

Just got my Komputerbay 64GB 1000x from Amazon and did a benchmark with my 5Dmk2.

At 16384k I only got 70.1 MB/s and 70.6 MB/s. Recording 1880x720. This seems abnormally, crazily low. Anybody have a

suggestion or recommendation. Am I testing incorrectly? Send card back I guess? Thanks in advance...

I'm trying to set my 128gb Komputerbay card in Macboot, but it's not recognizing it. Anyone else have trouble or am I missing a step? I followed the step on the site and it worked for one of my SD cards. Just not the CF card.

Would be interesting to see if deep level formatting of the CF-cards would increase writing performance and stability aswell. Not seeing it being discussed, but from what I read elsewhere this can really can impact the performance.

 

I don't have these cards myself yet, and this example is measured when photographing, so not directly comparable. Reading from this review the performance hit with the Transcend 1000x CF-card after deep formatting seemes interesting (note: read the whole review amazon review. he tests without the deep level formatting first).

Thanks for doing all this research on the cards Andrew. I just ordered a Komputerbay 64GB, I will come back and let you know the speeds I get when it is delivered.

A helpful warning to others using an EX-FAT formatted Komputerbay 64GB 150mb/s 1000x card on (certain) Macbook Pro's and Mac Pro's. I received my 64GB card and formatted it EX-Fat on my Windows PC to avoid the 4GB file limit.

 

I recorded a few shots of RAW footage but then the camera could not communicate with the card anymore. I tried formatting in camera but it wouldn't. Then I tried to use Disk Utility on my Mac but nothing worked. I also tried formatting the card on my PC but it saw no more than 32 MB.

 

I called Komputerbay and they said there was an issue with 64GB cards being corrupted on Mac's. They were very helpful and we tried to restore the card with software they suggested but to no avail. I can return the card and get a replacement or refund.

 

When I get my replacement I will dump the footage on my Windows pc and then transfer to my Mac for editing. Try to avoid connecting the 64GB card to your Mac (apparently the 32GB and 128GB cards don't have this problem) until they solve this issue.

 

(Worst thing is I never got to see my first RAW [email protected]!##!!)

What eveyone running the ML benchmarks need to bear in mind is whether live view is on or off. When it is off, your write and read speeds will be much faster, showing you the true write and read speed of the card.

 

My Komputerbay 1000x 64GB cards are faster than my Lexar 10000x 64GB card. Live view off I hit a peak write speed of 118.9MB/s, read speed of 150MB/s. With live on I hit a peak write speed of 95.5MB/s and a read speed of 121.8MB/s. I think I got lucky with an extremely fast batch of cards.

@JHines thanks for mentioning that, I was averaging 84MB/s write and 110MB/s in live view mode and now I am averaging 107.2MB/s Write and 137.3 Read speed as measured by Magic Lantern's benchmark card test.

First off, I would like to thank you guys for putting together this guide. I am having a problem with installing the ML onto my 5Dmark 3. I am running windows. Using the 64gig 1000x komputer card. I have followed the steps in the guide to the tee (1.13 firmware), and when I load the ML on to the card and use EOScard, then try installing the firmware, it just hangs and says it cannot find the firmware. I then I have to take out the battery out to get the camera to function again. I noticed that my card is exFat (image in the guide shows the card is FAT32). Is that the problem? If so, how do I fix that problem?

 

Thanks!

Henry

Nice. That's pretty much as good as it gets right now speed wise. I'm stoked on my 64GB Komputerbay cards. Hopefully they hold up over time, if not they come with a lifetime warranty according to Komputerbay so they should be able to be replaced if something were to happen. I bought 6 different 128GB Komputerbay cards hoping I'd find a fast one but had no luck finding any performance near what the 64GB cards write and read at. The best 128GB I've tested so far has been the Transcend 1000x.

I've bought 5 Komputerbay 1000x 64gb cards and I've currently been doing benchmark tests all day. 

 

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).

 

Am I performing the test correctly?

Alex T - turn focus peaking off! Disable everything that might hog the CPU like that. Just go with minimal global draw and nothing else like histogram, zebras, etc.

I got my komputerbay card working great now and thought I would share a raw vs H.264 video with you guys.

I'm on my third 64GB 1000x komputerbay now and all of them are nothing short of FAST. Very little variation in performance.

Im averaging 70mbs write w/ my komputerbay 64gb 1000x card w/ my 5d mk3  Pretty upsetting, i need to return/exchange it.

 

If you have a problem like this on the 64GB card it's likely you have a load of Magic Lantern features enabled such as focus peaking, anamorphic squeeze, etc.

Good to know I think I will be buying more of them.
