If you disable the RAID mode at RAID level 5 or 6, then every RAID array will be canceled. If you want to cancel only one of
RAID arrays in use, then go to the setup window and disable that specific RAID array.
`
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
-
When you build the RAID in level 5, the available capacity of a RAID is (the least HDD capacity) x (total number of HDDs -1).
-
When you build the RAID in level 6, the available capacity of a RAID is (the least HDD capacity) x (total number of HDDs -2).
-
If you use HDDs with different capacity, the HDD with the smallest capacity will be used to build a RAID.

`
Replace it with the same model of HDD or an HDD of the same capacity from the same manufacturer.
`
A HDD used to build the RAID should be one of the recommended models.
If it's not possible to use the same model of HDD, then use the HDD with the same capacity from the same manufacturer
should be used.
`
If you remove the power cord while using the RAID, it can damage it, so be careful.
For reliable power, it is recommended you use the UPS.
`
A new HDD to be replaced should be one that is not RAID configured.
