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.
•
RAID 5 Disk Volume
RAID 5 disk volume is ideal for organizations running databases and other
transaction-based applications that require storage efficiency and data protection.
To create a RAID 5 disk volume, a minimum of 3 hard disks are required. The total
capacity of RAID 5 disk volume = the size of the smallest capacity disk in the array x
(no. of hard disk – 1). It's recommended that you use same brand and same
capacity hard drive to establish the most efficient hard drive capacity.
Additionally, if your system contains four disk drives, three of them can be used to
implement RAID 5 data disks and the fourth drive can be used as a spare disk. That
way, in the event of a physical disk failure, the system will automatically use the
