The RAID10 target for mdadm will work on fewer disks - effectively it does striping and mirroring internally (think, in rough terms of >=2 stripes for each write, arranged such that each copy of a chunk is written to a different disk.) to the OP: However, I hardly see the point on only 2 disks. What will you gain from this that you don't gain from RAID1? you are more-or-less just striping twice, once in each direction, for each write. Stuart
