I hoped to integrate all discs in that raid.... I tried to run raid0 over pairs of the 18GB discs (leavin the fifth as spare) and run a raid 5 over these raid0's and the three 36gb drives, but that gives me 50mb/s reading as opposed to 100mb/s with 8*18GB raid5 on the same machine (three of these discs failed, so I got bigger ones). Why did I loose that much performance?
