Need for 90MB/s?

So, I'm putting in the order for a 5D mk II and I'm in need of a new CF card. (I have a 4GB - my D60 only used 2GB of that per its ability to format- and a 600MB - remember when a solid state 600MB card cost $500?)

I obviously need some new memory, so I'm looking at the 32GB Sandisk cards and they have an "Extreme Pro" product capable of 90MB/s...great...do I need this or will it outshine the rest of the gear?

I guess what I'm asking is, where is the bottleneck? How fast can the camera write to this media?

32GB is putting a lot of eggs in one basket should you have a card failure. Unless you were using a very high frame rate where clearing out the buffer could be an issue, slower cards (way cheaper) should suffice.

Hi,
I recently made a mistake and bought two Lexar platinum 200X cards. Slow!!!
I usually shoot with Sandisk extreme 60MB, the Lexar cards didn't write fast enough and I lost some shots waiting for the buffer to empty. Extremely frustrating at a wedding.
So I'm selling the Lexars and getting the new Sandisk Extreme pro.

On a side note why are you getting a 32 gig card? I don't shoot video just stills and I hate the fact that I can't get 8 gig Extreme pro cards hell I'd love to have 4 gigs. I like to split up the shoot on to different cards that way if a card goes bad I don't loose the entire shoot.

just my 2¢
good luck

I use 60mb/sec cards with 7D's and 1D4's. You cam get away with a 30mb/s for the 5D2 if you want to save money.

Cool, I went with the 16GB Extreme Pro...I'll get a second at some point.

Thanks.

90mb/s? Good for transferring from a USB 3.0 CF reader. Not much else. I'm happy with 60mb/s for significantly less.
