1:
Performance (One port 90Mb~110Mb)
With the same hardware, Linux based NAS
provides
far better performance (2 ~ 3 times) for
NFS clients and AFP
clients than Windows based NAS (60Mb)
2:
Compatibility
Besides performance, Windows based NAS
is still having issues providing NFS services
to NFS clients, and AFP services to AFP
clients.
So in an environment of more Linux/Unix
clients, or a
mixed of Linux/Unix, MAC, and Windows
clients environment, Linux NAS is the
only choice.
3:
Availability
Most of the virus attacks are Windows oriented.
Linux NAS has better resistant to that.
With Windows NAS, if not turn on the "auto
update", the IT might be afraid that
some important and critical updates are
needed from Microsoft. If turn on the "auto
update", almost every week, the Windows
NAS needs to be restarted so that the updates
can take effect.
With Linux NAS, you don't have this issue. 4.Monitors/Indicators
