You can create the disk volume of the following type:

z Single Disk Volume

Each disk will be used as a standalone disk. However, if a disk is damaged, all

data will be lost.

Note: If there is only one hard disk, please install it in the tray of HDD1.

z RAID 1 Mirroring Disk Volume

RAID 1 (mirroring disk) protects your data by automatically backing up the

contents of one drive onto the second drive of a mirrored pair. This protects

your data if one of the drives fails. Unfortunately, the storing capacity is equal

to a single drive, as the second drive is used to automatically back up the first.

Mirroring Disk is suitable for personal or corporate use to store important data.

z RAID 0 Striping Disk Volume

RAID 0 (striping disk) combines 2 or more drives into one larger disk. It offers

the fastest disk access but it does not have any protection of your data if the

striped array fails. The disk capacity equals the number of drives in the array

times the size of the smallest drive. Striping disk is usually used to maximize

your disk capacity or for fast disk access but not for storing important data.

z Linear Disk Volume

You can combine two or more disks into one larger disk. During file saving,

the file will be saved on physical disks sequentially but does not have a disk

failure file protection function. The overall capacity of linear disk is the sum of

all disks. Linear disk is generally used for storing large data and is not

appropriate to use for file protection of sensitive data.
