Enhanced JBOD:

JBOD (“Just a Bunch of Disks”) reports the individual drives. The operating system will see each drive in the JBOD mode

as a individual drive. There is no RAID protection in the JBOD mode. The JBOD mode allows the user to connect more

hard drives without taking up IDE connections on the motherboard.

JBOD: Spanned disk array without fault tolerance

Characteristics: Recommended use:

 JBOD reports individual disks.

 No fault-tolerance.

 Poorer I/O performance than RAID 0

 Storage capacity = Sum of constituent drive

capacities

 For most uses not

requiring fault

tolerance, RAID 0 is

better. JBOD has the

advantage if you are

using several drives

of different capacities.
