Page 11 / Chapter 3 - System Set Up
For the SAFE 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.
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).
SAFE (RAID 1 mirroring)
The drives show up as two volumes, each representing one set.
This mode requires 1 or 2 sets of 2 identical drives to
implement. RAID 1 creates an exact copy (or mirror) of a set of
data on the second drive. This is useful when reliability and
backup are more important than data capacity. The available
capacity to the user will be 50% of the total capacity for each
set but when one hard drive fails, it can be replaced and the
data rebuilt automatically.
SAFE II (RAID 10 mistriping)
The drives show up as one single volume. This mode requires
4 identical drives to implement. RAID 1 creates an exact copy
(or mirror) of a set of data. This is useful when reliability and
backup are more important than data capacity. The available
capacity to the user will only be as large as 50% of the total
capacity of all drives combined but when one hard drive fails, it
can be replaced and the data rebuilt automatically.
