2. What Is RAID
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. This card provides two RAID Set types, Striped (RAID 0) and Mirrored (RAID 1).
Disk Striping (RAID 0)
Striping is a performance-oriented, non-redundant data mapping technique. While Striping
is discussed as a RAID Set type, it is actually does not provide fault tolerance. With
modern SATA bus mastering technology, multiple I/O operations can be done in parallel,
enhancing performance. Striping arrays use multiple disks to form a larger virtual disk.
Disk Mirroring (RAID 1)
Disk mirroring creates an identical twin for a selected disk by having the data simultaneously
written to two disks. This redundancy provides instantaneous protection from a single disk
