p.2 #1 · CF card speed test "updated"


Lars where did you source the Transcend 400x UDMA 7 cards? BH shows images of the Transcend with UDMA written on it and not UDMA 7. They are also described as being UDMA 6 cards. On Transcend's site the 64GB 400x UDMA and UDMA 7 cards share the same part number.

Are you planning to get Lexar 64GB memory cards at 800x and 1000x speeds? Based on your results of the UDMA 7 400x cards it is safe to assume that Transcend 600x and 1000x UDMA7 cards will have nearly the same number of shots for a 30 sec burst.

Amazon have the 64GB 400x UDMA 7 cards at these prices

60MB/s read & 45MB/s write Lexar $99.59
90MB/s read & 60MB/s write Transcend $103.98

With a 128GB UDMA7 card you can have these many RAWs & L JPEGs. These figures were based on what was written in each body's manual.

L JPEGs
1D X & C - 19,200
1D4 - 22,144
5D3 - 16,160
5D2 - 19,840
7D - 18,976

RAW
1D X & C - 4,480
1D4 - 5,600
5D3 - 4,160
5D2 - 4,608
7D - 4,960

Divide by half to get how many images can be taken with a 64GB UDMA card.

Before CF5.0 spec the max capacity was 256GB.

Here's the two types of Transcend cards I use. The 32GB says UDMA 7 and 400x, but they're fairly old. I bought the 32GB cards from B&H in March 2012. They might be using new labeling now.

[edit: change 2011 to 2012 - what difference a '1' can make ]

Amazon have

The cards that don't have UDMA 7 written on them are older and not UDMA 7. It's a huge difference in speed between them as you can see in my test. it's the same card but the older card was made before UDMA 7 existed.
They should look like Jim's pictures when you buy them. I buy most of my cards from Amazon.de and Amazon.uk. And they have stopped selling those Transcend UDMA 6 cards a long time ago.
I will probably not get the Lexar 800x and 1000x cards. The Lexar 1000x is maybe the fastest card you can buy. I have not compared it against the Transcend 1000x. The Lexar 800x is not much faster than the 400x cards. Only the read specs are 800x. The write speed is about 400x.

I would also belive there is a much larger difference between the 600x and 1000x cards when using the 1DX camera. That's my first impression when I have used them in my 1DX.

I ordered mine after may 2011 and still received the udma6 copy. It's ok. I'll try my luck with the 64gb 400x cards.

I don't belive there existed any Transcend UDMA 7 cards in May 2011 (I'm pretty sure) I belive Jim got the dates wrong The Europen and Thai shops where I have bought mine (mostly Amazon.de and Amazon.uk) didn't have any of those UDMA 7 cards until summer 2012.
I don't even belive UDMA 7 cards (any brand) have existed for nearly two years

I got my 32GB 400x UDMA6 card last November 2011 at $66.50 from BH with my Lexar USB 3 UDMA card reader.

While reading up on UDMA7 on google i found this UDMA7 vs UDMA6 comparison review.

http://blog.willshootphotography.com/2012/06/udma-7-cf-card-performance-on-canon-5d-mark-iii-and-1d-mark-iv-soooo-worth-it.html

Sandisk announced their 128GB UDMA7 card last January 2011 for $1,500.

I am just happy that jcolwell was able to snag UDMA7 cards early.

I am still undecided on getting the 64GB 400x UDMA7 card as it does not comply with the 4K requirement of 100MB/s write speed.

Canon came out with firmware that improves the writing/reading speeds when using UDMA 7-compatible CF cards for the following EOS bodies.

7D Firmware Version 1.2.5 on Wednesday, April 20, 2011
5D Mark II Firmware Version 2.0.9 on Sunday, May 29, 2011
1D Mark IV Firmware Version 1.1.0 on Monday, May 30, 2011
50D DSLR Firmware Version 1.0.8 on Tuesday, June 28, 2011

Was out playing with my 1d this morning. With a Lexar 64gb 400x udma7 card I was getting around 132-135 Raw images in 30 seconds...not too bad for a cheap(er) card and 2.5 gigs of data...

Yet another 64GB Transcend 400x UDMA 7 CF card review with Windows-based write/read benchmarks.

http://www.jayceooi.com/2012/10/31/64gb-transcend-400x-compactflash-card-review/

The link below has the 128GB Lexar 800x at speed of 56MB/s write & 126MB/s read.

http://www.youtube.com/watch?v=DuKLt4suJTM

Read speeds north of 40MB/s should be of interest to computer users with FW800
Read speeds north of 80MB/s should be of interest to computer users with USB 3.

That's great, but the files are very small when shooting with the 1D body.

Lars if you have time can you perform a write/read benchmark of your Transcend 128GB UDMA 7 1000x and Transcend 64GB UDMA 7 600x with your computer? Kindly indicate what card reader you used, whether Mac or pc, usb 2, 3 or FireWire 800 and ssd or hdd.

I have a 16gb photofast 533x plus that write/reads at 90MB/s way back in 2010. Got hooked on the speed.

I'm staying in Bangkok a few months so it's not possible. I only have a small old Notebook here. My good PC, cardreaders and all the other stuff is in Sweden.
I have only tested the cards for write speed in the camera. And I will do that with the 1DX also. The read speed and upload time to my PC have never really interested me. For me it doesn't matter if it takes 4,6 or 8 minutes to upload the pics to my PC. And I have so many cards that I can shoot a few months without uploading the pics to my PC
PhotoFast are good cards. But I don't belive they have been upgraded for a long time

Lars you are correct. Photofast hasnt updated any of their CF card since I got mine in 2010.

I did a write/read bench using a Lexar USB 3 UDMA7 dual slot card reader connected via USB 3 to a 2012 MBAir Core i7 and I was getting 18MB/s write/reads via Black Magic Design Disk Speed Test for Mac.

I was expecting write/reads of 90MB/s or so.

BTW are you getting a 600 IS II in Bangkok? If you are how much is it going for?

Something must be wrong if you only get 18mb/s. I get more than that with nearly every card and a USB 2 reader. I also have the Lexar dual slot USB 3 reader normally.
I'm not getting the 600 II lens. I have already bought too much in the last month. 1DX and two lenses.
He asked if i like the 600II when I bought the 1DX in the FotoFile shop here in Bangkok. He like to have about $ 11,600 for it.

Yes. It was March 2012. Sorry for the confusion. I just noticed the updates to this thread.

your results will vary quite a bit especially if your USB port which today they are is on the PCIe bus. as the PCIe path is used by more then one signal there will be a variation of data flow due to bandwidth limitations. this occurs on my i7 laptop too with both my built in SD reader and USB ports. the more you do the less gets through.

Well, there should be one PCIe lane for 2 USB 3.0 ports. You should get about 175MB/sec. sustained on one port.

that's the trouble with specs they generally don't take in account of the whole deal working at once. not thru the chipset where things get interesting. it all depends on what's going on at the time.

I used to buy Lexar exclusively but over the past year I've had two od their pro USB readers and the hub for it fail, plus one of the cf/sdusb card readers and their express cf card reader fail to work or outright die. I switched to the hood an raw steel line since without problems.

Hej Lars

Thank a lot for posting this, that really helped.

Thanks to you I'll soon buy a couple of Transcend 400x 64Go that cost half of the 600x "explicitely UDMA7" that I may have bought otherwise. I'll take the 400x from Amazon Japan so with their turnover I am sure I'll get UDMA 7 versions and not some very old UDMA 6 stock. I'll put them in the 1Dx and probably never open the CF door again for years

Anyway, thanks again for testing and sharing, you made the decision simple

Regards

Alain

I always buy from Amazon UK and Amazon DE. They have the latest cards and rather good prices also.
