Chapter 3 - System Set Up / Page 10
If the total capacity
exceeds 2TB and
your Operating
System does not
support single
volumes over 2TB,
set the 2TB switch
to position B and it
will automatically
split the volumes
(A+B / C+D).
For the FAST mode,
hard drives of
identical capacities
are recommended.
If different, the total
amount of the
space that can be
used will depend on
the drive with the
smallest capacity.
BIG (JBOD spanning)
The drives show up as one large single volume. Spanning is an
array (not RAID) that is written sequentially across the drives.
By itself, it does not provide any performance or redundancy
benefits. Use this if you have installed 1-4 hard drives with
different capacities.
FAST (RAID 0 sstriping)
The drives show up as one large single volume. This mode
requires 4 identical drives to implement. Used where speed is
the primary objective, RAID Level 0 (also called striping) is not
redundant. This form of array splits each piece of data across
the drives in segments; since data is written without any form of
parity data-checking, it allows for the fastest data transfer of all
other modes. However, if one drive becomes damaged, the
whole array can become corrupted.
