RAID MODES
A Redundant Array of Independent (or Inexpensive) Disks (RAID) is a system
that utilizes multiple hard drives to share or replicate data among the disks. The
benefit, depending on the selected RAID Mode (combinations of disks), is one or
more of increased data integrity, fault-tolerance, throughput or capacity when
compared to single drives.
Deleting the current partition prior to changing RAID modes is highly
recommended.
Using identical hard disks with the same capacity and RPM, and from the
same manufacturer are highly recommended for best capacity utilization.
RAID 0 (Striping)
RAID 0 (Striping) is a performance-oriented, non-redundant data mapping
technique. It combines multiple hard drives into a single logical System. Instead
of seeing several different hard drives, the operating system sees only one large
drive. Striping splits data evenly across two or more disks simultaneously,
dramatically increasing performance.
Striping can be implemented in disks of differing sizes, but the storage space
added to the array by each disk is limited to the size of the smallest disk.
Although Striping is an easily implemented and simple configuration, Striping
should never be used for mission critical applications. The speed of operation is
fast in comparison to other RAID modes.

In Striping mode, if one disk in the RAID System fails, all data in both
installed disks will be lost.
