RAID status : Displays the operational status of the RAID.
- Active : Signals the fact that the RAID is operating normally.
- Degraded : It is displayed when the one or more HDDs that make up the RAID are malfunctioning. When
the maximum number of HDDs allowed in the RAID level are malfunctioning, if an additional HDD
malfunctions, you cannot use or restore the RAID.
Immediately, replace the HDD and proceed with restoration.

- Rebuilding : Rebuilding: Indicates that the RAID array is in the recovery process. At RAID level 5 or 6, if the

`
If the status of HDD is displayed as inspected/replaced in the device/format page, you cannot use it to build a RAID.
`
When the RAID mode is in use, it is recommended to use HDDs with the same storage space from the same manufacturer.
`
If you enable or disable the RAID mode, existing data will be deleted. You make sure to backup your data.

RAID Array capacity calculation
-
If RAID is configured for level 1, then one array of RAIDs is allocated with the smallest HDD size.
-
If you use HDDs with different capacity, the HDD with the smallest capacity will be used to build a RAID.
