RAID - Redundant Array of Independent Disks
RAID technology manages multiple disk drives to enhance I/O performance
and provide redundancy in order to withstand the failure of any individual member,
without loss of data. SATA RAID provides two RAID Set types, Striping (RAID 0) and
Mirroring (RAID 1).
RAID 0 (Striping)
Striping is a performance-oriented, non-redundant data mapping technique.
While Striping is discussed as a RAID Set type, it actually does not provide fault
tolerance. Striping arrays use multiple disks to form a larger virtual disk.
RAID 1 (Mirroring)
Disk mirroring creates an identical twin for a selected disk by having the data
simultaneously written to two disks. This redundancy provides instantaneous pro-
tection from a single disk failure. If a read failure occurs on one drive, the system
reads the data from the other drive.
