Asus P5VD2 VM - SE Motherboard - Micro ATX - RAID Configurations

ASUS P5VD2-VM/P5V-VM SE DH 3-7
3.3 RAID congurations
The motherboard supports the following RAID congurations.
RAID 0 (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. Use of two new identical hard disk drives
is required for this setup.
RAID 1 (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 conguration provides data protection and
increases fault tolerance to the entire system. Use two new drives or use an
existing drive and a new drive for this setup. The new drive must be of the same
size or larger than the existing drive.
JBOD (Spanning) stands for Just a Bunch of Disks and refers to hard disk drives
that are not yet congured as a RAID set. This conguration stores the same
data redundantly on multiple disks that appear as a single disk on the operating
system. Spanning does not deliver any advantage over using separate disks
independently and does not provide fault tolerance or other RAID performance
benets.
