MSI A55M-P35 - Manual (Page 63)

The ntegrate one SATA host controller separately, and
support RAID functon for performance and relablty.
The SATA RAID provdes support for RAID 0 (Strpng),
RAID 1 (Mrrorng) & RAID 10 (Strpng & Mrrorng) .
RAID 0 greatly mproves hard dsk I/O performance by
concurrently strpng data across multple drves. RAID
1 makes sure data s not lost f a drve fals as data s s-
multaneously wrtten to two drves. Drves configured for
RAID Strpng are sad to form a RAID 0 set, whle drves
configured 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.
