You can set the storage volume as JBOD, RAID 0, RAID 1, RAID 5, RAID 6 or
RAID 10. 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
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.
RAID 1 Offers disk mirroring. Provides twice the read rate of single
disks, but same write rate. RAID 1 requires a minimum of 2
disks.
RAID 5 Data striping and stripe error correction information provided.
RAID 5 requires a minimum of 3 disks. RAID 5 can sustain one
failed disk.
