create a third array that is RAID 1 using the two RAID 0 arrays for it's
devices.
This would be a RAID 0+1, stripped set's mirror together. RAID 1+0 is mirrored disk sets stripped together.
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).
