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 HDDs with the same capacity and RPM, and from the same
manufacturer are highly recommended for best capacity utilization.
RAID O (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.
