1.3.1 NRAID
Disk Spanning
NRAID stands for Non-RAID. The capacity of all drives is combined to become one logical drive
(no block striping). In other words, the capacity of the logical drive is the total capacity of the
physical member drives. NRAID does not provide data redundancy.

1.3.2 JBOD
Single Drive Control
JBOD stands for Just a Bunch of Drives. The controller treats each drive as a stand-alone disk;
therefore, each drive is an independent logical drive. JBOD does not provide data redundancy.
