RAID 10:
RAID 10 combines the advantages (and
disadvantages) of RAID 0 and RAID 1 in
one single system. It provides security
by mirroring all data on a secondary set
of disks (disk 3 and 4 in the drawing
below) while using striping across each
set of disks to speed up data transfers.

set of disks to speed up data transfers.
Features and Benefits
Drives: Minimum 4, and maximum is 6 or 8, depending on the platform.
Benefits: Optimizes for both fault tolerance and performance, allowing for automatic
redundancy. May be simultaneously used with other RAID levels in an array, and
allows for spare disks.
redundancy. May be simultaneously used with other RAID levels in an array, and

Drawbacks: Requires twice the available disk space for data redundancy, the same
as RAID level 1.
as RAID level 1.
Fault Tolerance: Yes.
RAID 5:
A RAID 5 array can withstand a single
disk failure without losing data or access
to data. Although RAID 5 can be
achieved in software, a hardware
controller is recommended. Often extra
cache memory is used on these
controllers to improve the write
performance.
