RAID Mode
The enclosure can be set to function in one of four modes;
Normal, JBOD, RAID 0,
and
RAID 1
, giving you the flexibility to access your data in whatever way works best
for you. The available modes are described below, with their corresponding dip switch
setting displayed on the left side of the image.
Normal Mode –
This mode treats both hard drives as separate disks, allowing them to
be accessed independently of each other. Your computer will recognize them as if they
were flash drives being plugged into separate USB ports, not changing them in any
way.

JBOD Mode –
This mode combines the two hard drives into one large drive for the
purpose of increased storage space. Data is stored on one drive at a time, so when
the first one is full, the next one begins to be used. The computer’s operating system
will recognize them as a single drive.
RAID 0 Mode –
This mode combines the two hard drives into one large drive for the
dual purpose of increased storage space and performance. In this mode, data is split
amongst the two drives simultaneously, improving the read/write performance. The risk
in using this mode is that failure of one disk will result in total data loss. When using
this mode, it is recommended that you use hard drives with the same capacities. If
hard drives of different capacities are used, the smaller hard drive will be doubled in
size, with the remaining space on the larger hard drive going unused.
