MSI 990XA-GD55 series

The ntegrate one SATA host controller separately, and
support RAID functon for performance and relablty.
SB950 SATA RAID provdes support for RAID 0 (Strp-
ng), RAID 1 (Mrrorng), RAID 10 (Strpng & Mrrorng)
& RAID 5 (strpng wth party). RAID 0 greatly mproves
hard dsk I/O performance by concurrently strpng data
across multple drves. RAID 1 makes sure data s not
lost f a drve fals as data s smultaneously wrtten to
two drves. Drves con󰘰gured for RAID Strpng are sad
to form a RAID 0 set, whle drves con󰘰gured for RAID
Mrrorng are sad to form a RAID 1 set. RAID 10 s mple-
mented as a mrrored array whose segments are RAID
0 arrays. RAID 10 has same fault tolerance as mrrorng
and reduces overhead by strpng. It needs at least four
drves to form a RAID 10. RAID 5 de󰘰nes technques for
party data.
