All but one of them uses hardware raid 5 (Controlled by an HSZ40 in a DEC storage works cab.) It is DEFINATELY faster than the one which has NT controlled RAID 5. Hardware controlled & software controlled sets are both same sizes on each server. This difference is phenomenal. Aside from mere disk access - you should see how much CPU time is used keeping the RAID set working on the software controlled one.. I'll never setup software RAID again. 2. If Linux can see SCSI disks (which it can) it's all just a matter of plugging your SCSI cable into a hardware RAID box (such as the Digital Storage Works cabinets). The hardware controller takes care of everything. Linux will just see it as one huge disk. You will however need to spend an extra half-an-hour setting up the controller (It'll be done through a dumb terminal - and it's dead easy).
