Description
The storage volume is a single HDD with no RAID support. JBOD
requires a minimum of 1 disk.
Provides data striping but no redundancy. Improves
performance but not data safety. RAID 0 requires a minimum of
2 disks.
Offers disk mirroring. Provides twice the read rate of single
disks, but same write rate. RAID 1 requires a minimum of 2
disks.
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.
If the administrator improperly removes a hard disk that should not be removed
when RAID status is Degraded, all data will be lost.
