Hi,
If you consider using ROON, then you can forget the idea of connecting directly storage capacity to the NB. You should better connect storage capacity to any device running the ROON server or any device running an upnp server (Minim server is the one recommended by dCS).
If you do that you shall enjoy playing music flawlessly on your dCS gear.
I use a Qnap 453dx as Roon and minim server, I use both Mosaic and Roon. It works great and it is 100% silent.
