3.4 RAID 0 / RAID 1 / JBOD configurations The motherboard includes a high performance IDE RAID controller integrated in the VIA® VT8237 southbridge chipset. It supports RAID 0, RAID 1 and JBOD 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. JBOD (for "just a bunch of disks" or sometimes "just a bunch of drives") is officially termed as "spanning". This is used to refer to a computer's hard disks that haven't been configured according the RAID system to increase fault tolerance and improved data access performance. This RAID system stores the same data redundantly on multiple drives by combining the drives into one larger logical drive. ASUS A7V600 SE Motherboard 3-7

RAID 0 / RAID 1 / JBOD configurations
The motherboard includes a high performance IDE RAID controller integrated in
the VIA
®
VT8237 southbridge chipset. It supports RAID 0, RAID 1 and JBOD 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.
JBOD
(for “
just a bunch of disks
” or sometimes “
just a bunch of drives
”) is officially
termed as “
spanning
”. This is used to refer to a computer’s hard disks that haven’t
been configured according the RAID system to increase fault tolerance and
improved data access performance. This RAID system stores the same data
redundantly on multiple drives by combining the drives into one larger logical drive.
