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

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. 
There may be differences in SQ running bdp2 as roon endpoint vs. playing your music straight off the hard drive that’s connected to the bdp2 using Bryston’s software or web interface. That’s why I brought up the set up I did with the Auralic in my earlier post. So if your system is resolving and you sit down for a critical listening session you may discover things you don’t like about the sound of roon. YMMV but that is my experience. However, as a database and a UI, I’ve not seen anything better than Roon yet.
