body structure, which can be simply connected to the PC by either
USB2.0 or eSATA. It supports 2 SATA HDDs with entirely screw free

MODE:
z Dual Mode: 2 HDDs appear on your computer and can be used
/ accessed simultaneously
z JBOD Mode: Y our computer displays 1 HDD with the capacity
of two HDDs combined
z Raid 0 Mode**: T his mode involves no redundancy and splits
the files equally into each HDD. The advantage of this mode is
the data transfer speed, but the disadvantage is data might be
damaged if one of the HDDs is defect.
z Raid 1 Mode** (mirroring): O ne HDD has its data duplicated
on another HDD. If either drive fails, the other continues to
function as a single drive and thus provides full redundancy.

mirroring and the rest is used for Raid 0.
z SAFE33 Mode*

1/3 (33%) of the HDD volume is used for
mirroring and the rest is used for Raid 0.
