System Software
Your computer may already come with system software
pre-installed. Where this is not the case, or where you are
re-configuring your computer for a different system, you
will find this manual refers to
Microsoft
Windows 7 and

HDD RAID Support (Model C Only)
Your hard disk(s) can be set up in AHCI mode or RAID
mode (for increased performance or protection). Note that
setting up your hard disk(s) in RAID mode needs to be
done prior to installing the
Windows
OS.

RAID Setup for Windows 7
(Model C Only)
You may use your hard disks in combination with Striping
(RAID 0), Mirroring (RAID 1), or Recovery for either
fault tolerance or performance.
Table 2 - RAID Description
RAID Level
Description
RAID 0
(at lease two
hard disks
needed)
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 0 (a striped array) is not fault-tolerant. The
failure of one drive will result in the loss of all data
in the array.
RAID 1
(at lease two
hard disks
needed)
Identical drives in a mirrored configuration used to
protect data
. Should a drive that is part of a mir-
rored 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.
RAID 1 (mirrored array) provides full data protec-
tion, as data can simply be copied from a healthy
disk to a replacement for any failed disk.
Recovery
(at lease two
hard disks
needed)
Two identical drives copying data between a mas-
ter and a recovery disk. This provides more control
over how data is copied between the master and
recovery drives, fast volume updates and the abil-
ity to view the data in
Windows Explorer
.
