you create, manage, and delete a JBOD the same as a logical drive. You can designate from two to four physical
drives with online capacity expansion. If you attach a single physical drive that was previously partitioned, RAIDXpert
will recognize it as a JBOD. However, RAIDXpert does not allow you to create a single-drive JBOD.
RAID Ready
RAID Ready arranges individual physical drives the same as if they were attached to the PC’s motherboard controller.
The advantage is that the AMD SB7
5
0 Controller can accommodate up to four physical drives, more than most PC
motherboards. As a single physical drive, RAID Ready does not offer the performance or security advantages of other
RAID logical drives. However, you can create a backup drive by: Inserting an unformatted physical drive or
designating an installed physical drive. In RAIDXpert, you create, manage, and delete a RAID Ready the same as a
logical drive. A RAID Ready logical drive has only one physical drive. You can designate from one to four of your
physical drives as RAID Ready.

RAID Configurations Precautions
1.
Please use two new drives if you are creating a RAID 0 (striping) array for performance. It is recommended
to use two SATA drives of the same size. If you use two drives of different sizes, the smaller capacity hard
disk will be the base storage size for each drive. For example, if one hard disk has an 80GB storage
capacity and the other hard disk has 60GB, the maximum storage capacity for the 80GB-drive becomes
60GB, and the total storage capacity for this RAID 0 set is 120GB.
2.
You may use two new drives, or use an existing drive and a new drive to create a RAID 1 (mirroring) array
for data protection (the new drive must be of the same size or larger than the existing drive). If you use two
drives of different sizes, the smaller capacity hard disk will be the base storage size. For example, if one
hard disk has an 80GB storage capacity and the other hard disk has 60GB, the maximum storage capacity
for the RAID 1 set is 60GB.
3.
Please verify the status of your hard disks before you set up your new RAID array.
WARNING!!
Please backup your data first before you create RAID functions. In the process you create RAID, the system will ask if you
want to “Clear Disk Data” or not. It is recommended to select “Yes”, and then your future data building will operate under a
clean environment.

Installing Windows XP / XP 64-bit / Vista / Vista 64-bit With RAID Functions
If you want to install Windows XP, Windows XP 64-bit, Windows Vista or Windows Vista 64-bit on a RAID disk
composed of 2 or more SATA / SATAII HDDs with RAID functions, please follow below procedures according to the
OS you install.
