Spanned volume

A spanned volume is a formatted partition in which data is stored on more than one hard disk drive or solid-state drive, yet appears as a single volume.

A spanned volume is a non-RAID drive architecture, and may be implemented in hardware or software; It may be referred to as Concatenation, SPAN, BIG, or JBOD, though JBOD is ambiguous because it may also refer to each physical disk being presented as a separate logical volume.
