Alright, if youve read my other posts I have 1 hard drive that failed (primary) and 2 other HD's (1 80 gig, 1 40 gig). I bought a new hard drive (250 gig) and I am going to move my system into a new case. I was going to RAID the 3 drives until I realized it would reduce the 250 gig into a 40 gig puke: So, I think I'm going to just keep the 250 gig un-RAID'ed. Now, I just need some advice. I am willing to RAID the 80+40 so the 80 is reduced to 40, and just leave the 250 gigger in an IDE port. Is that even possible? Also, what would be the smartest thing to do? Would I get the best performance if I installed the new O/S on one of the RAID drives and used the 250 simply for storage? What would you guys do if you were me: New case, 1 blank 250 gig, 1 used 80 gig, 1 used 40 gig? Also, if I were to do the 40/80 gig RAID and the 250 gig IDE would I simply plug the 80 into RAID 1, the 40 into RAID 2, and the 250 into one of the IDE's? Is that how I would go about doing it?
