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.
