Which UDMA cards are you getting?

It's said the 7D performs best with UDMA cards. But searching for UDMA cards I found different specs (133x, 300x, 366x, 533x, other have it marked in MB/s, like 45MB/s), I found UDMA enabled, which I'm not sure what is and i definitely found several brands like Photofast, Transcend, Sandisk (Photofast is the cheaper, I wonder if it's as good?)

What cards are you getting?

I went with 1 Kingston 32GB 133x, non-UDMA. If I have problems, I'll step up, but it seems people seem to be more than happy shooting 133x non-UDMA.

x2 I'll add a 16GB Sandisk III UDMA if I have any problems at all but I won't be shooting raw in burst mode and I won't be snapping stills while I'm recording video, so I really don't anticipate any problems at all with the Kingston 32GB 133x.
 
I went with SanDisk Extreme IV's after I heard some people were experiencing dropouts with non-UDMA cards. Only somewhat affordable after SanDisk rebate which just expired.
 
I was going to get two Kingston 16GBs 133x, but then decided to get one 32GB 133x instead. Since it is slightly faster it might help a tad for RAW bursts. I'll pick up a second one soon. Hopefully 64GB cards will come out in force soon, and make 32's a bit cheaper before I buy the second.

SanDisk has some new rebates up through Jan 2010, http://www.adorama.com/catalog.tpl?op=rebates&brand=SanDisk still ridiculously pricy.

I'm going to gamble and buy a 200x rated 16gb "Centon" card on sale from Frys for $39.99 and see how it performs.
 
I did 3x SanDisk 8GB Extreme IV (45mb/sec) UDMA's.

One card limits you, no matter how big. When it's full you have to stop to dump.
Two cards can be done but it's tight.
With three cards, called A, B and C...

A is shooting
B is resting
C is dumping

Always one in resting, ready to go. I would have gone for the 16GB's, but the 8GB's were a DEAL! Through that rebate, I got them for $34 a piece! Incredible.
 
I also got the SanDisk Extreme IV 8GBs with the deal, came up to $99 after rebate.

I like the versatility of having 3 as well. 24 minutes per card is good enough for me!

I do agree that three is best. And 4 or 5 offer additional safety in case some bozo lost one, or if any of them were to die on you for whatever reason. Being able to shoot non stop is key when you are spending lots of money. Same goes for batteries.

I am going to get just two large ones for myself, but first I would like to try one out and see how they perform with 8fps RAW stills. Also, I don't need anything more than 48 in one ATM so I can wait till I need it for a job and hope they drop.
 
Sounds fast. The Kingston is rated at 20MB. As it was said before the camera needs significantly less than 10MB for video.

Anything over 5.5MB/s should be fast enough for video recording.

A little more is nice to have for safety, but the Kingston is supposed to be reliable already.

Now for RAW 8fps bursts I have no clue what the requirements are. But I would assume that up to a certain point faster is better. The photos are stored on a built in memory buffer though, so all that would be affected is the offload of the buffer to the CF. If there offload were faster than your card's write speed, then a faster card would allow you to continue shooting sooner.

Well, it really depends on your workflow and your type of work. If I had a single 64GB card chances are I would never fill it up in a day, so I could dump in the evening and have it fresh for the next day.
In any case I definitely don't see the need for 3 cards. I mean, how long does it take to transfer the files to a computer? It could work with 2, like one shooting and the other dumping. Off course, the more cards the better, but I rather have bigger cards and not dump as often than having to dump every 12 or 24 minutes.
