RAID Level Description
RAID 0
Identical drives reading and writing data in parallel to increase performance. RAID 0
implements a striped disk array and the data is broken into blocks and each block is
written to a separate disk drive.
RAID 1
Identical drives in a mirrored configuration used to protect data. Should a drive that is
part of a mirrored array fail, the mirrored drive (which contains identical data) will
handle all the data. When a new replacement drive is installed, data to the new drive is
rebuilt from the mirrored drive to restore fault tolerance.
Recovery
Two Identical drives copying data between a master and a recovery disk. This provides
more control over how data is copied between the master and recovery drives, fast
volume updates and the ability to view the data in Windows Explorer.

Array Types
A Mirrored Array
(RAID 1) provides full
data protection, as
data can simply be
copied from a healthy
disk to a replacement
for any failed disk.
A Striped Array
(RAID 0) is NOT fault-
tolerant. The failure of
one drive will result in
the loss of all data in
the array. It is de-
signed to increase disk
performance by
spreading the I/O load
across the channels
and drives.

SATA Mode Selection
The SATA mode selection should be made before installing your operating system.
DO NOT change your selected SATA mode unless you intend to reinstall your operating
system. Make sure you have backed up all your data before doing so.
