SB750 SATA RAID
The integrated SATA host controller separately, and
support RAID function for performance and reliability.
SB750 SATA RAID (SATA1~6) provides support for RAID
0 (Striping), RAID 1 (Mirroring), RAID 10 (Striping &
Mirroring) & RAID 5 (striping with parity). RAID 0 greatly
improves hard disk I/O performance by concurrently
striping data across multiple drives. RAID 1 makes sure
data is not lost if a drive fails as data is simultaneously
written to two drives. Drives configured for RAID Strip-
ing are said to form a RAID 0 set, while drives configured
for RAID Mirroring are said to form a RAID 1 set. RAID
10 is implemented as a mirrored array whose segments
are RAID 0 arrays. RAID 10 has same fault tolerance
as mirroring and reduces overhead by striping. It needs
at least four drives to form a RAID 10. RAID 5 defines
techniques for parity data.
