RAID Group Managem ent
Users can expand a RAID group, add hard drive(s) to a RAID group, migrate a RAID
group, configure a spare drive, enable a bitmap and recover a RAID group for a chosen
volume, while the data contained in the RAID group remains intact.
RAID group types
Refer to the table below for explanations on RAID types:
Field
Description
Single
Disk
A single, stand-alone RAID group can be set up for your NAS.
However, this setup does not provide any redundancy protection.
So, in the event that a disk is corrupted or otherwise damaged, all
data on that disk will be lost.
RAID 0
Striping
A striping RAID group combines two or more disks into one large,
logical disk. It offers the fastest disk access performance but no
data redundancy protection in the event of disk failure or damage.
The disk capacity is the sum of all disks. Disk striping is usually used
to maximize disk capacity or accelerate the speed of disk access.
Please note that the RAID 0 configuration is not recommended for
storing sensitive data.
RAID 1
Mirroring
Disk Mirroring protects your data by automatically mirroring the
contents of one disk to the second disk in the mirrored pair. It
provides protection in the event of a single disk failure. The storage
capacity is equal to the capacity of the smallest single disk, as the
second disk drive is used to back up the first disk drive. The RAID 1
configuration is suitable for storing sensitive data on a corporate or
personal level.
RAID 5
The RAID 5 configuration is ideal for organizations running databases
and other transaction-based applications that require storage
efficiency and data protection. A minimum of 3 hard disks are
required to create a RAID 5 group. The total capacity of the RAID 5
group is equal to the size of the disk with the smallest capacity in
the array times the number of (hard disk – 1). It is recommended
(though not required) that only hard drives of the same brand and
capacity are used to establish the most efficient hard drive capacity.
