monitor and change the RAID array on the OMNINAS.

Single
A single hard drive is used. All data is lost in the event of a hard drive failure.
JBOD
RAID functionality is not available in JBOD (Just a Bunch of Disks) mode. Data is written sequentially
on the designated disks. Both hard drives are combined to form a single larger disk.
Note:
If you are using two identical HDDs, it is recommended to use RAID 0.
RAID 0
Both hard drives are combined and the available capacity of each disk is added into a single logical
volume. Redundancy or parity is not available. RAID 0 offers the best performance, however, there is
no disk failure protection.
IMPORTANT:
If a single disk in RAID 0 fails, the data in both disks is inaccessible due to the RAID 0 cross-disk writ-
ing function.
RAID 1
Dual hard drives are required. RAID 1 is a secure mode, providing mirroring functionality. The data
is duplicated between both HDDs, and, in the event of a single disk failure, the data is available in
the healthy disk. RAID 1 is recommended for disk failure protection. However, available disk space is
reduced by 50% due to the mirroring function.
Only RAID 1 supports hot-swap functionality. All other modes require you to power down the device
before removal of hard drives.
