LaCie 2big USB 3.0 • DESIGN BY NEIL POULTON User Manual 3.1.2. JBOD (Just a bunch of disks) When the 2big USB 3.0 is set to JBOD, each drive is considered a separate device, similar to individual hard disk drives. Each disk will mount on your computer as separate hard drives, divided into the partitions created by your operating system's disk management utility. One great advantage of JBOD is the use of the full capacity of both drives. Also, in the event of a single drive failure, files stored on the healthy drive are not lost. However, this configuration offers none of the benefits of RAID 0 (speed) or RAID 1 (complete data protection). Applications JBOD can be used with any application. In the event of a single drive failure, files on the healthy drive will not be lost. However, choosing to forgo RAID 0 and RAID 1 does have its drawbacks since superior performance or total data security will not be available.

Make certain that all transfers on both drives are finished before removing either disk. Removing or adding a drive in JBOD Mode Power Off Insert or remove one or both disks as listed in 3.3.
