About RAID

RAID 10

This dual-level RAID type is created by using two or more equal-

sized RAID 1 arrays to create a RAID 0. Both read and write

performance are improved due to array striping. However, the

performance improvement costs additional storage space due to

the mirroring of the arrays.
