The integrate one SATA host controller separately, and
support RAID function for performance and reliability.
AMD RAID provides support for RAID 0 (Striping), RAID
1 (Mirroring) & RAID 10 (Striping & Mirroring). RAID 0
greatly improves hard disk I/O performance by concur-
rently striping data across multiple drives. RAID 1 makes
sure data is not lost if a drive fails as data is simultane-
ously written to two drives. Drives configured for RAID
Striping are said to form a RAID 0 set, while drives con-
figured for RAID Mirroring are said to form a RAID 1 set.
RAID 10 is implemented as a mirrored array whose seg-
ments are RAID 0 arrays. RAID 10 has same fault toler-
ance as mirroring and reduces overhead by striping. It
needs at least four drives to form a RAID 10.
