AMD RAID
The ntegrate one SATA host controller separately, and
support RAID functon for performance and relablty.
AMD SATA RAID provdes support for RAID 0 (Strp-
ng), RAID 1 (Mrrorng), RAID 10 (Strpng & Mrrorng)
& RAID 5 (strpng wth party for SB850 only). RAID 0
greatly mproves hard dsk I/O performance by concur-
rently strpng data across multple drves. RAID 1 makes
sure data s not lost f a drve fals as data s smultane-
ously wrtten to two drves. Drves configured for RAID
Strpng are sad to form a RAID 0 set, whle drves con-
figured for RAID Mrrorng are sad to form a RAID 1
set. RAID 10 s mplemented as a mrrored array whose
segments are RAID 0 arrays. RAID 10 has same fault
tolerance as mrrorng and reduces overhead by strpng.
It needs at least four drves to form a RAID 10. RAID 5
defines technques for party data (for SB850 only).
