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.
