Raid 0+1 with 3 hard drives?

[Sidetracker]

Can I run Raid 0+1 with two 20GB HD's(Raid 0)and one 46GB HD(Raid 1)? They will all be IBM Deskstar 75GXP's @7200rpm. The motherboard is an ABIT KT7A-Raid.

hmmm.. i have the same baord running raid 0 with 2 75gxp's. im pretty sure that all the drives should be the same? or if the one you are backin up to is the bigger one that should be ok too.. not totally sure but i think thats how it works.

I belive if you want Raid 0+1 you are going to need 4 drives. Raid 1 is basically a mirror. Raid 0 is not fault tolerant Raid 1 is. So if you want to have fault tolerance, you would need to mirror both drives.
