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
