I haven't benchmarked anything like that in a while. I'm not saying that RAID 0 with 3 targets is going to be non-performant, but I would expect a parallel array to be better for random ops unless a classroom workload falls into sequential for some reason (software installation). Do you have any numbers testing this, or better, real world stats?
