You can create the following disk volumes:
•
Single Disk Volume
Each disk will be used as a standalone disk. However, if a disk is damaged, all data will
be lost.
•
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.
•
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.
•
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.
