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 manage-

ment 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 con-

ﬁguration offers none of the beneﬁts of RAID 0 (speed) or RAID 1

(complete data protection).

IMPORTANT NOTE: Removing a drive in JBOD mode requires

that the user stop accessing data from the 2big USB 3.0. Make

certain that all transfers on both drives are ﬁnished before remov-

ing either disk.

Removing or adding a drive in JBOD Mode

Power Off

Insert or remove one or both disks as listed in 3.3. Removing and

Installing Drives.

Power On

The icon(s) for a disk that was removed might remain visible in My

Computer/Computer (Windows) or the desktop (Mac). While the

icon may remain, data will no longer be accessible since the disk

has been removed.

To avoid leaving a trace icon when using a JBOD conﬁguration,

LaCie recommends unmounting and/or shutting down the 2big

USB 3.0 before removing a drive. See sections 2.3. Disconnect-

ing Your Hard Drive and 3.3. Removing and Installing Drives for

more information.

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.
