RAID 10
RAID 10 is a striped configuration with RAID 1 seg-
ments whose segments are RAID 1 arrays. This confi-
guration has the same fault tolerance as RAID 1, and
has the same overhead for fault-tolerance as mirroring
alone. RAID 10 achieves high input / output rates by
striping RAID 1 segments. In some instances, a RAID
10 configuration can sustain multiple simultaneous drive
failure. A minimum of four hard disk drives is required
for this setup.
RAID 5
RAID 5 stripes both data and parity information across
three or more hard disk drives. Among the advantages
of RAID 5 configuration include better HDD perfor-
mance, fault tolerance, and higher storage capacity.
The RAID 5 configuration is best suited for transaction
processing, relational database applications, enterprise
resource planning, and other business systems. Use
a minimum of three identical hard disk drives for this
setup.
