The integrate one SATA host controller separately, and
support RAID function for performance and reliability.
SB710 SATA RAID (SATA1~6) provides support for
RAID 0 (Striping), RAID 1 (Mirroring) & RAID 10 (Striping
& Mirroring). RAID 0 greatly improves hard disk I/O per-
formance 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
congured for RAID Striping are said to form a RAID 0
set, while drives congured for RAID Mirroring are said
to form a RAID 1 set. RAID 10 is implemented as a mir-
rored 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.
