Introduction

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

protection from a single disk failure. If a read failure occurs on one drive, the

system reads the data from the other drive.

RAID 10 (Disk Mirroring and Striping)

RAID 10 combines the features of both RAID 0 and RAID 1. Performance

is provided through the use of Striping (RAID 0), while adding the fault

tolerance of Mirroring (RAID 1). The implementation of RAID 10 requires four

drives. The drives are assigned as two sets of striped pairs.
