utilization, we suggest the best use of the two disks which are the

same brand, same capacity, and same cache.

access to exactly the same performance on a single disk access

operation. JBOD does not provide data security. It simply provides a

method of using disk space, JBOD storage capacity equal to the

composition of the sum of the capacity of all disks.
