RAID 5 requires a minimum of 3 disks. RAID 5 can sustain one
failed disk.
RAID 6 Two independent parity computations must be used in order to
provide protection against double disk failure. Two different
algorithms are employed to achieve this purpose. RAID 6 requires
a minimum of 4 disks. RAID 6 can sustain two failed disks.
RAID 10 RAID 10 has high reliability and high performance. RAID 10 is
implemented as a striped array whose segments are RAID 1
arrays. It has the fault tolerance of RAID 1 and the performance of
RAID 0. RAID 10 requires 4 disks. RAID 10 can sustain two failed
disks.
If the administrator improperly removes a hard disk that should not be
removed when RAID status is degraded, all data will be lost.
