RAID 10 - Combination of RAID 1 and RAID 0

RAID 10 is a combination of RAID 0 (Performance) and RAID 1 (Data Security). Unlike RAID 4
and RAID 5, there is no need to calculate parity information. RAID 10 disk arrays offer good
performance and data security (Figure 6). As in RAID 0, optimum performance is achieved in
highly sequential load situations. Identical to RAID 1, 50% of the installed capacity is lost through
redundancy. RAID 10 requires a minimum of four disks.
