I have grabbed 3 80GB drives and a 160GB drive in order to do some ‘quick’ raid testing on the Coraid rack. It has 15 slots and only 5 were being used by 750GB drives so that left plenty of slots open. I will be creating and destroying raids over and over so working with smaller drives makes things go much faster. Just initializing the 3 80GB drives into a Raid5 took the rack right around an hour. If I did that with 3 750GB drives it would drastically inhibit my evaluation and testing.
