3.1.2. JBOD (Just a bunch of disks)
When the 2big USB 3.0 is set to JBOD, each drive is considered
a separate device, similar to individual hard disk drives. Each disk
will mount on your computer as separate hard drives, divided into
the partitions created by your operating system’s disk manage-
ment utility. One great advantage of JBOD is the use of the full
capacity of both drives. Also, in the event of a single drive failure,
files stored on the healthy drive are not lost. However, this con-
figuration offers none of the benefits of RAID 0 (speed) or RAID 1
(complete data protection).

Applications
JBOD can be used with any application. In the event of
a single drive failure, files on the healthy drive will not be
lost. However, choosing to forgo RAID 0 and RAID 1 does
have its drawbacks since superior performance or total data
security will not be available.
