RAID Mode
The enclosure can be configured to operate in one of three modes (Normal/JBOD,
RAID 0, RAID 1). Switching between the different modes is accomplished through the
jumper and reset button located on the inside of the enclosure.
Mode Jumper Position Description
Normal
Normal (JBOD) leaves
the hard drives as
independent disks.
The operating system
will treat them each
separately.
Different sized hard drives
can be used in this mode.
RAID 0
RAID 0 (Stripe) combines
both hard drives into a
single large disk array.
Data is split in half
evenly across each disk
simultaneously. Read/
write performance is
increased as a result as is
disk capacity, but failure
of any one disk will result
in permanent and total
data loss.
Identical hard drives must
be used in this mode.
RAID 1
RAID 1 (Mirror) writes the
same data to both hard
drives, creating mirror
copies. This provides
redundancy in case
one drive fails, but only
provides one drive worth
of storage space.
Identical hard drives must
be used in this mode.
