So, my question is: should I go for the 2.5" disk setup or 3.5" disk setup, and does the raid setup in either case look correct?
Afaik they are about equal in speed. With the smaller ones being a bit faster in random access and the larger ones a bit faster for sequential reads/writes.
My guess is that the 8x 2.5" configuration will be faster than the 6x 3.5", even if the 3.5"-drives happen to be faster they probably aren't 50% faster... So since you don't need the larger storage capacities that 3.5" offer, I'd go with the 8x 2.5"-setup.
