Thanks so much for passing that along, Cannon. It's a new site to me! (Wow, that fellow really did an exhaustive analysis.) I'll certainly use it for reference in buying my next CF card.

I went to that site . . . sheesh, you could spend days sifitng all the info.
Right now I don't have that kind of time.

My question is for anyone who has had the time to research
and owns a Canon 10D.

Which card (1 gig or more) is quickest?

SanDisk Ultra. The SanDisk Extreme is the next fastest (and a bit cheaper). I've been using a Lexar 1G with 32x write acceleration for a year and haven't found myself tapping my toe.

Thanks so much Ken. You probably saved me a couple of hours.

I have a 1 gig microdrive and have had no issues despite the numberous
warnings and alerts, but with wildlife photography an increase in
speed would be always welcome.
