JBOD: JBOD lets you combine multiple disks of mixed capacities into a single
logical storage device. The capacity of the JBOD array is the sum of the total
capacities of the individual component disks (that is, it does not have the limitation
of RAID0 where you lose some capacity when using mixed sized disks). JBOD
offers no performance increase compared to the component disks. It has lower
reliability than the component disks, as the failure of a single disk results, in
general, in the failure of the whole array. Depending on how you create volumes on
the JBOD array, you may be able to recover data when one or more disks in the
JBOD fail. This, however, is not guaranteed.
