Quick roon question


Currently I run a Bryston bdp2 streamer with a USB SSD attached for storage. My windows laptop controls the Bryston through the Bryston network app.

If I go to Roon would I connect the USB drive to the Bryston or to my laptop?

Thanks

Are those of you using Roon happy with it. I am not unhappy with the very simple stock Bryston media player. I just thought I would try something different. 
I am quite happy using Roon. It’s doing exactly what I want which is Simply presenting my own digital music along with favorite records from Qobuz as one collection that I can search and combine to playlists etc. Then it plays in sync to my four different zones. That’s all I need.
Everything else Roon does is just extra... the information and links to related artists and music is great plus layers of other options I never even consider using.
In my original post I mention I am using a Bryston bdp2. 

I am considering purchasing a second bdp2 for my second system. Will Roon figure out which is which? And give me the option of playing either  bdp2 #1 or  bdp2 #2. 
Yes, it should figure out which is which they will have different IP addresses,  you might name them system 1 and system 2 or something more intuitive like family room and kitchen.
