I will be buying a new pair of 32GB CF cards for the 1Dx tomorrow and I'm trying to figure out how to throw my money at this problem.

I've searched here and elsewhere and haven't reached a firm conclusion about which makes and models are really at or near the top of the heap so I'd love to hear some opinions before I commit.

Also, I'm only looking at 3 e-tailers for this but I'm always happy to hear of other trustworthy sources.

The options on the table (so far) are:


  1. Lexar 32GB 1000x UDMA 7. (claimed 145MB/s Write, 150MB/s Read) - $428.50 for a 2-pack at store B.
  2. Delkin 32GB 1000x UDMA 7 (claimed 50 MB/s Write, 150MB/s Read) - $199 each at Store A (Oddly, their UDMA 6 Combat Flash is rated faster and is more expensive while the regular UDMA 6 is faster and cheaper. /sigh)
  3. Sandisk 32GB Extreme Pro UDMA 6 (claimed 90 MB/s R/W) - $149.95 each at store A. I couldn't find a Sandisk UDMA 7 card in this size at any of the stores I checked.
  4. Transcend 32GB 600x UDMA 7 (claimed 87MB/s Write, 92MB/s Read) $99.95 at store C.
From the claimed performance specs of the above and elsewhere it really doesn't seem like UDMA 7 adds anything other than price and the "it goes to 11" bragging rights.

I own cards from Sandisk, Lexar and Transcend and all have been perfect except for one warranty replacement on a Lexar card so I really don't have any brand loyalty.

I'm just looking for a reliable card that will keep the new 1D running smoothly.

Please help a poor, confused shopper out with your experience, advice or commentary.

Thank you in advance...

(I did search for threads on this topic and if I've missed one please accept my apologies.)

I have always used Sandisk and had great luck with them. If I were in the market today that is what I would buy.

I use Lexar 600x 32GB at Oshkosh this year shooting the ditch..... No problem keeping up with the 1D4 s (I used 2 of them) and the 7D. You get about 3 frames a second write speed. Really for those who look at stuff on paper, they don't consider how fast that REALLY IS...... So a 1000x may get you 4 frames a second..... To do that sustained is very rare (I shot like 6 cards in 2 hours or so). Thats a lot of shooting.

Sandisk or Transcend here; although, I'd recommend considering 16 or even 8GB as your upper end for capacity. Just in case you have a failure there are fewer images (per card) that can get lost...plus, 2 x 16GB or 4 x 8GB can usually be had a fair bit cheaper than a single 32.

Over the past several years, I have used the Transcend 16 gb and 32gb 400x CF cards. The MK III has 300K on the shutter and the 7D 160K...all images captured with the Transcend cards. Not a single bug-a-boo.

I thought the price of the cards was fair as compared to some other cards. I also use a Delkins USB 3 card reader to transfer the images to the PC.

Happy on this end.
Hope this helps.

I've considered that, for sure, but I've set up the camera for redundancy every time I've been out. Either I mirror the cards or I write .jpg to one and RAW to the other so I'm more worried about losing things (camera or cards) than I am of failure.

Add to that the fact that I've missed more shots due to "Card Full" (several) than I've ever lost to a card failure (1 partial image after recovery on that aforementioned Lexar that was replaced.)

The main reason I'm going for 32 is that I do shoot video sometimes and need the space for that.

Thank you all who have replied so far. I'm surprised nobody has mentioned anything about UDMA 6 vs. 7 yet...

Just to close the loop, but hopefully not discussion, I chose the Sandisk Extreme Pro cards. UDMA 6, yes, but claimed faster than some of the UDMA 7 claims and more realistic, IMO, than the Lexar numbers.

I trust Sandisk to deliver and to stand behind their product.

Plus I saved over $100 relative to most of the others... :)

Thanks!

To support max burst rates and minimize download times, I use Lexar 32GB 1000x in my 5DIII and Lexar 32GB 600x in my 7D. For both I use a Lexar dual slot USB 3 reader that is updated for UDMA 7.

Rob Galbraith memory speed tests with the 7D and 5DII and 1DIV all show Lexar CF to be at the top of the heap for write speeds.

Erik - I also went for Sandisk Extreme Pro 32s for my 1DX (4 of them). Two of mine are branded UDMA 7, the other 2 UDMA 6.

Yep, I had two of them plus my wife's cards to download one evening. Thank goodness for UDMA 7 cards and readers talking to laptops over USB 3. It would be painfully slow with UDAM 6 cards over USB 2 or FW.
