RAID 1+0
RAID 1+0 combines RAID 0 and RAID 1to offer mirroring and disk striping. Using
RAID 1+0 is a time-saving feature that enables you to configure a large number of
disks for mirroring in one step. It is not a standard RAID level option that you can
select; it does not appear in the list of RAID level options supported by the
controller. If four or more disk drives are chosen for a RAID 1 logical drive, RAID
1+0 is performed automatically.
