RAID congurations
If your device supports Intel® Rapid Storage Technology, you can create
RAID 0 or RAID 1 congurations.
RAID denitions
RAID 0 (Data striping) optimizes two identical storage devices to
read and write data in parallel, interleaved stacks. Two storage devices
perform the same work as a single drive but at a sustained data transfer
rate, double that of a single storage device alone, thus improving data
access and storage. Use of two new identical storage devices 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.
