VIA RAID configurations
The motherboard includes a high performance IDE RAID controller
integrated in the VIA VT8237 southbridge chipset. It supports RAID 0 and
RAID 1 with two independent Serial ATA channels.
RAID 0 (called data striping) optimizes two identical hard disk drives to
read and write data in parallel, interleaved stacks. Two hard disks perform
the same work as a single drive but at a sustained data transfer rate,
double that of a single disk alone, thus improving data access and
storage.
RAID 1 (called data mirroring) copies and maintains an identical image of
data from one drive to a second drive. If one drive fails, the disk array
management software directs all applications to the surviving drive as it
contains a complete copy of the data in the other drive. This RAID
configuration provides data protection and increases fault tolerance to the
entire system.
