Storage Smarts Answer #18

Were you correct? This week's answer is:
d. JBOD

Learn more:

JBOD (for "just a bunch of disks," or sometimes "just a bunch of drives") is a derogatory term - the official term is "spanning" - used to refer to a computer's hard disks that haven't been configured according to the RAID (for "redundant array of independent disks") system to increase fault tolerance and improve data access performance.

The RAID system stores the same data redundantly on multiple disks that nevertheless appear to the operating system as a single disk. Although, JBOD also makes the disks appear to be a single one, it accomplishes that by combining the drives into one larger logical one. JBOD doesn't deliver any advantages over using separate disks independently and doesn't provide any of the fault tolerance or performance benefits of RAID.
