RAID Level
You can set the storage volume as either None, JBOD, RAID 0, RAID 1 or
RAID 5. RAID configuration is usually required only when you first set up the
device. A brief description of each RAID setting follows:
RAID Levels
Level Description
None There is no existing storage volume.
JBOD The storage volume is a single HDD with no RAID support. JBOD
requires a minimum of 1 disk.
RAID 0 Provides data striping but no redundancy. Improves
performance but not data safety. RAID 0 requires a minimum of
2 disks.
