Here's a nice review of the currently available CF and SD cards. Seems not much has changed from the 2+ years ago when I got my Nikon D70 and did homework on which cards are best: Lexar and Sandisk are still on top, most everything else is a wash.
If you're put-off by the 19 pages (mostly images and graphs), here's a summary:
- - Unless you're sure your device works with 4G+, stick with 2G or smaller due to various incompatibilities.
- - Getting the fastest cards out there is usually unnecessary, since your device probably can't write that fast anyway.
- - The speed ratings (eg "100X") are mostly bogus, based on ideal scenarios not likely to occur.
- - "Ranked as the best card for overall average read and write speeds, the 4GB Lexar Professional CompactFlash 133X card with Write Acceleration is our preferred choice."
- - If you're looking for 2GB in SD format, Lexar Professional SD 2GB 133X is the best, with the Kingston SD Ultimate 2GB 120X not too far behind.
