Quoth Jim C. Nasby: > I'd suggest whichever one is a stripe of mirrors (you don't want a > mirror of 2 stripe sets). RAID 1+0 (also incorrectly referred to as "10") is a stripe of mirrors. RAID 0+1 is a mirror of stripes. Jim is right; the difference is subtle yet important when one or more disks fail. Regards, David Drum david@mu.org -- "Penultimate." Ooh! Second-best word ever!--Frazz
