Setting the RAID function

The RAID function must be set when a new HDD has been installed. RAID1 mode: The same data is written simultaneously onto two HDDs.

The data safety is ensured by data redundancy (mirroring).

When HDDs with different memory sizes are combined, the smaller memory size will be used. JBOD mode: The data is written onto only the specified HDD.

Use this mode when storing large amounts of data. This screen displays in several TAB screen as the following.
