RAID 10, a combination of RAID 1 and RAID 0, has mirrored drives.
It breaks up data into smaller blocks, then stripes the blocks of data to
each RAID 1 drive group. Each RAID 1 drive group then duplicates its
data to its other drive. The size of each block is determined by the stripe
size parameter, which is 64 Kbytes. RAID 10 can sustain one drive failure
in each drive group while maintaining data integrity.
