RAID Levels
RAID (Redundant Array of Independent Disks) allows multiple physical drives to be combined together
in a disk array. Then all or a portion of the disk array is formed into a logical drive. The operating system
sees the logical drive as a single storage device, and treats it as such.
RAID 0 – Stripe
When a logical drive is striped, the read and write blocks of data are interleaved between the sectors
of multiple physical drives. Performance is increased, since the workload is balanced between drives
or “members” that form the logical drive. Identical drives are recommended for performance as well as
datastorageefciency.
