My music files are on a 7200 RPM spinning drive in an external enclosure that I share on my network. I have not had any issues with lag or anything else when streaming to my Node 2. And I'm sending files over my wireless network, the connection is not hard-wired.
I don't doubt that having it hard wired and connected directly to the streamer might have some benefit, but the DAC is probably the weakest link in the chain if you're going with a Bluesound product, not the hard drive.
