Raid 10 requires 4 drives. First you would make two RAID 0 arrays, then create a third array that is RAID 1 using the two RAID 0 arrays for it's devices. With only two drives, your option is RAID 1 (mirroring - proper redundancy) or RAID 0 (striping only - lose one drive and you lose *all* data). -- Digimer E-Mail: linux at alteeve.com AN!Whitepapers: http://alteeve.com Node Assassin: http://nodeassassin.org
