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.
