of 4
TB
(or more) for

Combine
the

If
y
o
u
are
using two

HDDs, it is
recommended
to use
RAID
0
for
optimised
performance.
RAID
1 (mirroring): The
data
is
duplicated
on two
phy
s
ical
disks. In the
event
of
a single
disk failure,
the complete data
is
still
available
on the
working
disk. KD21
supports hot-swapping
and auto-rebuild

tionality
without
having
to turn off
the
NAS.

Robust aluminium chassis with a clean and modern look
KD21 is built of
a 2.5mm
thick stylish
aluminium housing that
not
only
blends
well with
home environments,
it
moreover
is of
technical benefit
- it is also

Temperature/°C
Reliable, cool and quiet
With the
above
in
mind,
the inside
temperature
doesn
’
t
increase
easily.
The fan
will
never
turn on when the
hard
disks’
temperature
is
below
the
threshold value
of 55°C [2]. Should the
uncommon case
of
higher
temperatures
arise, the
large 70mm cooling
fan starts
spin
n
i
n
g
at a
comfortably
low
speed
to
keep
the system
quiet.
