The goal would be to get rid of Windows altogether. Hell, I'd like to get rid of my Windows workstation too, ideally just run a linux VM on the Unraid server that a remote into from an RPi or something. Either way, that's a long way down the road. The first step is to migrate the server.
And yeah, I'm not too concerned about drive performance unless it means it will be REALLY bad, meaning people can't stream shit, and that's what I'm asking about. Finally, at least with my limited exposure, Windows Docker sucks.
