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 drive(s) 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 unit. 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, simple configuration, Striping should
never be used for mission critical applications. The speed of operation is
excellent in comparison to other RAID modes.

When you choose to insert only two hard drives, there is not limitation on
the order of hard drive insertion or the slot number. Under Basic Setup Menu, if
inserted all four hard drives, all will be assigned as the same mode.
In Striping mode, if one disk in the RAID System fails, all data in installed
disks will be lost.
