Sorry mate... already moved 600Gb of data onto the Raid5 array, then realised I should have a small Raid0 for my XP install, so moved it all back off again, created it, and now put it all back on again... If I wasn't flying away for 2 weeks Sunday I would do it in a heartbeat, but pressures are mounting... got to sort 4 x PC's to take so I can give them away, all sorts of other local stuff to arrange, etc, etc... I'm sure you'll understand.
When I get back (2 1/2 wks)... I will blow the Vista install away on the Raptors, and do a quick XP install on the same sized Raid0 on the Raptors just for fun, and compare that to the Seagate one, before I reinstate the Vista image to a smaller Raid0. How would that be?
