3.1.2. BIG (Concatenation)
■
In Big mode, the two physical disks are combined
(concatenation) so that one single yet larger logical vol-
ume mounts on the desktop, offering maximum possible
capacity (the available capacities of each disk are cumu-
lated).
ImpOrTANT INfO:
data of both disks become inaccessible.
Offers the maximum possible capacity by combining
the capacities of two drives into one large volume.
3.1.3. JBOD
■
In JBOD mode ( Just a Bunch of Disks), the two
physical disks work as two independent hard drives in
one single housing so that two logical volumes mount
on the desktop.
ImpOrTANT INfO:
are become inaccessible, but the second disk continues
to work independently.
In certain configuration, using a powerful computer
with under-exploited resources, JBOD mode can be
faster than Fast mode when using the native RAID 0
software of the computer operating system.
