Supported 1000x CF cards for continuous RAW recording

[pind]

Those are my  Test  results ?

I am not sure if this is good or bad results?  SHould i send back the CF card for exchange  or  its ok to keep this  card ??

Hi all.
Just got a new Mk III and loaded ML last night. I have a Sandisk Extreme Pro 64GB CF Card 160MB/s, 1066x
and I have RAW 1080p recording perfectly without dropped frames. Seems to record at 93Mb/s very well.

Hi Guys, sorry for this as it's probably been asked a million times....

what is an acceptable speed for the Komputerbay 64gb to write? by this i mean what speed should the benchmark show before i send it back for another..?

Currently my car writes at

90
90
90
82
76
72
61
18

is there any speed difference between sandisk extreme pro 160 16-32-64 gb?
And like the same transcend.
choosing between transcend 32 1000x and sandisk 160 16gb.

Regarding Transcend 64GB 1000x.
I will return mine, because I think it is very unstable in its performance. It's like it is fast only at certain areas on the card, like if its only fast first time you write data on it, then it gets slow. I don't know if this is correlated but my card is very slow the first 2 GB (only 300 frames before framedrop) then it records continuously for about 10 min.

 If I benchmark the card i get very various results - but at the moment only between 35-80MB/s write speed.

The store will have the card replaced for another of their brands if I wish. I am Thinking of adding some money and go for a Sandisk 100mb/s (according to test data that card is above 83mb/s write, and so sufficient for 1856x844 RAW recording on my 5Dmkii).

Hi guys,

I just installed ML on my 7d, I have 64gb Komputerbay card. I ran the test in ML and it showed write speed around 50 megabytes /sec which horrified me but when I shoot raw (live view on) in 1728x972 it says continuous recording ok and the speed is around 73 mb some times, other around 68mb. So how is such a difference between actual shooting and test in ML possible? I guess I'll have to return the card but just want to make sure I am not doing something the wrong way? Thanks!

Running card benchmark will create a file on your card. Look for BENCHx.PPM (x=0,1,2, ...).
Unload all modules, turn off global draw and give it another run. Upload latest file and link it if you want us to take a look.

lexar 800x 64gb
70mb/s in crystaldisc
66mb/s in movie mode with GD on, small hacks on
can record 1920x818/25 continuous, 1920x1080/25 for 8secs
..im saving to buy some good cards

I changed my Transcend 64GB 1000x to a Sandisk 128GB 100MB/s 667x. The Sandisk performed better with continuous recording @1856x842 2.20:1 with sound. Decided to change the Sandisk to a 1067x Sandisk Extreme Pro 150MB/s to get highest performance possible on the 5D2.

I made benchmarks of the all the cards, even the ones i returned. If anyone has some collection of ppm-files feel free to add these:  http://snk.to/f-cdul6p3u

Transcend 1000x 64GB - the first faulty card I had (maybe its not representative for Transcend)
Sandisk 128GB 100MB/s 667x - my first exchange, turned out to be a bit slow for highest setting on my 5D2
Sandisk Extreme Pro 64GB 150MB/s 1067x - Rock solid with very stable rates regardless of buffer settings etc.

OK so here's what ML test says for my Komputerbay 64gb 1000x (all modules turned off, along with global draw). Live view was on.


it seems I got the short stick and will be returning it to amazon however, when recording raw in 1728x972 it never drops frames and speed varies between 65 and 73. With camera temperature rising speed slows down, but I'm not sure if this is caused by the camera or the card.

Looks like somethings wrong with the url. Write speeds are:
51,7
50,8
55
54
55,4
55,8
60.3
60,5

quite below the promised speed indeed...

Very, very old build!
Download latest nightly and try again in playback mode.

[andrei12]

Thanks a lot, Walter! As you can see from this, the results were quite good this time (latest nightly build, modules and global draw OFF, playback mode) :



However, I then turned everything ON and the result is quite different (and by far the worst):



after that I tried shooting raw at 1728x972 with Global draw and modules on and it could shoot for just a couple of seconds before stopping automatically, displaying 1 dropped frame message. How can this be explained? With the old build I never had dropped frames for minutes of shooting? Is it the card or is it the build?

Hello everyone!

Recently I bought KomputerBay 128GB 1066x CF and don't know if it's ok or broken...

Is this benchmark good or bad?

[poromaa]

Is this benchmark good or bad?

I would say it looks very good. If you record some raw with the debug on you can see a buffer graph. Look if it is stable or very volatile. Try record a couple of times to the card, format it, and see if the speed is changing. If not I think you made a very good purchase. Is it 5Dmk3?
edit: (can be seen in the pic). It would be nice to see how fast the Sandisk 160MB/s is on a 5Dmk3)

When GLOBAL DRAW is OFF you should get 115-120MB/s Write speed in playback, which would be in line with benches from KB and my own results.

Thx. Well, Sandisk CF Cards in Poland are insanelly expensive so i don't have any possibility to help...
After recording about 40gigs of RAW and formating card is still above 100mb/s at this first lines of benchmark.

When GLOBAL DRAW is OFF you should get 115-120MB/s Write speed in playback, which would be in line with benches from KB and my own results.

Well... 112-115mb/s with GD off.

Little advice for me please. What to buy:

Lexar Professional 32GB 1066x Speed 160MB/s   or   SanDisk Extreme Pro CompactFlash 32 GB, 160 MB/s?

thx

[Walter Schulz]

For 7D?

[Markus]

Komputerbay 1066x 256gb are also a great option. Especially for the mkIII. ☺

[Casi]

I used a Sandisk Extreme Pro 32GB 160MB/s UDMA 7 for RAW recording on a 5D Mark III and it appears that 24fps @ 1080p is the fastest I can record without dropping frames.

I would like to record 1080p with 30fps - which card can handle that and still be reliable?

Some responses here mention that the Komputerbay 1066X cards are not very stable.

Is Lexar's 1066x Professional CF the fastest and most reliable out there at the moment?

Thanks in advance.

Frame dropping with recorded file size (summarized) < 4 GByte or above?

[Casi]

Frame dropping with recorded file size (summarized) < 4 GByte or above?

Walter, was this directed at me?

If so, my file sizes have always been below 2 GB. I get frame drops within 5-20 seconds roughly.

[Brawl]

yes Walter for 7D! thx!
