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:
None There is no existing storage volume.
JBOD The storage volume is a single HDD with no RAID support. A minimum of 2 HDD is required.
RAID 0 Provides data striping but no redundancy. Improves performance but not data safety. At least 2
HDD are required.
RAID 1 Offers disk mirroring. Provides twice the read rate of single disks, but same write rate.
Supports 2 HDD.
RAID 5 Data striping and stripe error correction information provided. Excellent performance and good
fault tolerance.
