If you enable the RAID (Redundant Array of Independent Disks) mode, when a system HDD is damaged you
can restore data safely. The NVR supports RAID level 5 and 6. RAID Level 5 supported by the NVR can work to
restore data for a single HDD only in case of failure of that HDD. RAID level 6 can restore data and operation of
up to two malfunctioning HDDs.
In this NVR, you can organize two RAID. The first RAID uses only the HDDs installed in HDD slot 1 to 6, and the second RAID
`
M
uses only the HDDs installed in HDD slot 7 to 12.
If the RAID has 5~6 HDDs installed, you can operate and organize it.
`
You can use RAID level 6 only if a single RAID has 6 HDDs mounted in it.
