JBOD - Single Drive
An alternative to RAID, Just a Bunch of Disks (JBOD) capacity is equal to the
sum of all drives in the group, even if the drives are of different sizes. JBOD
appears in the User Interface as one or more individual drives. There are no
performance or fault-tolerance features. When a disk fails, all data on the disk is
lost. Other disks are unaffected.
