Two built-in Superspeed USB 3.0 ports and Card Reader 
The 
OMNINAS 
K
D
21
features 
two 
USB 
3.0  ports  
and one 
USB 
2.0  port.  
USB
3.0  
achieves a 
maximum 
data rate 
of  up  to 
5.0Gbps 
(640  
MB
ytes/sec)
which  is ten  times  faster  
than 
USB 
2.0.  
USB 
3.0  is fully 
compatible 
to 
USB
2.0.  
All USB 
ports  
support external devices 
like 
hard 
disks,  flash 
drives,
printers,  
digita
l
cameras, etc. 
The 
memory can  be shared  across local 
networks.  
I
n
a
ddition,
 the  built-in 
card reader reads 
your SD 
cards 
and 
shares 
such  
data 
with the  
NAS 
swiftly. 
Low power consumption 
When  using  
the 
OMNINAS 
KD21 in 
a 
home  environment 
it likely 
rests 
most  of the  tim
e
 in 
suspend mode and 
the  
average con
s
umption
should be  more 
or  less  9,6  W only.  
Based 
on  this 
value, the 
annual 
consumption 
would  
amount 
to 
approx. 
84 kWh which  would  
mean 
j
u
st
17 Euros on  
the power 
bill 
(based 
on  20 Euro ct/kWh). 
U
n
der
normal 
load 
(idle 
mode), 
the  KD21 
consumes 
19 W. 
Acronis True Image Backup Software 
The 
OMNINAS 
KD21 
comes bundled 
with 
a copy 
of  Acronis True 
Image
Personal 
Edition 
software. 
This 
utility 
provides 
powerful  
data 
backup
capabilities 
that  
support 
full 
backups 
or 
selected backups 
of  key files, 
enhanced 
flexibility 
and convenience 
of 
data 
backups.
