RAID Level
You can set the storage volume as 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
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.
Excellent performance and good fault tolerance. RAID 5 requires
a minimum of 3 disks. RAID 5 can sustain one failed disk.
WARNING
If the administrator improperly removes a hard disk that should not be removed
when RAID status is Degraded, all data will be lost.
