JBOD
In JBOD mode, the two disk drives function independently of one
another. JBOD is an acronym for Just a Bunch of Disks.
Figure 3. In JBOD mode, both disks will appear on your computer.
Span (Big)
Span mode links the two disk drives, so they function as a single drive
with combined storage space. This mode is similar to RAID 0 mode,
but it does not stripe the data across the disks. Span mode is not as
fast as RAID 0, but it is more secure.
