IIRC there were a few issues connecting large HHD directly to the SBTouch due to the limited memory of the onboard SBServer.
However, I think if this is the first time using a streaming device then the route Ronnie suggests is a good one.

If the setup works and pleases then the user can make some more informed decisions.

What will happen is that the user is likely to be very surprised by the high level of SQ and user-friendliness.
