Roon is not officially supported on any NAS, as far as I know. If you choose to install it there, you do so at your own risk and with the understanding that the software will not function optimally. That being said, there are several Linux guys that have been working on hacking it onto various NAS’ with differing levels of success.
Most NAS’, including your own, are under-powered to be running RoonServer or Roon as a server.
Minimum:
Intel Core i3, Ivy Bridge
4GB RAM
SSD boot drive
Roon Server needs lots of fast cache and space. It will need at least 2 GB space for each 1,000 albums on your boot drive. See the following link, which talks about PC requirements which is what the NAS would have to equal:
