SanDisk for the Nikon D90 I just purchased a Nikon D90. What is the difference between the SanDisk Extreme Class 10 and the SanDisk Extreme iii Class 6? Which is newer and which is better for my camera?
Class 10 will write and read faster than Class 6. Class 10 is newer, too.
If you check out the review page for the Sandisk Extreme Class 10 8gb SD card, there is a reviewer who has tested the D90 with various versions of these cards. Here's a link to his review: http://www.amazon.com/review/RZMLVQAAY104H/ref=cm_cr_rdp_perm . This might be helpful for you in making your decision.
