Just a followup on this. Last place I worked we had a bunch of Dell 2600 boxen with Adaptec RAID controllers. Due to the horribly unreliable behaviour of these machines with those controllers (random lockups etc...) we switched off the RAID and went to software mirror sets under linux. The machines because very stable, and as an added bonus, the performance was higher as well.
