NRAID
Disk Spanning
NRAID stands for Non-RAID. The capacity of all the drives are
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 drives. NRAID does not provide data redundancy.
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.
