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.
