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.
