RAID Level
Identical drives reading and writing data in parallel to increase performance. RAID 0
RAID 0 implements a striped disk array and the data is broken into blocks and each block is
written to a separate disk drive.
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
RAID 1
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.
Two Identical drives copying data between a master and a recovery disk. This provides
Recovery 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.
Prepare the following before setting up your serial ATA hard disks in RAID mode:
1. The Microsoft Windows 7 OS DVD.
2. A hard disk installed in the Primary HDD bay.
AND
A second (identical) hard disk installed in the Secondary HDD bay.
3. The Device Drivers & Utilities + User's Manual disc.
Note that if you are using Advanced format hard disks that have a 4KB physical
sector size, and you are installing a Windows 7 release pre Service Pack 1, you will
need to install a driver from the Device Drivers & Utilities + User's Manual disc at
OS installation (see page

data can simply be
copied from a healthy

A
(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

spreading the I/O load
across the channels
and drives.
