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. |
