indeed; each of these are not router issues or features, especially the HDMI connection - - that's a video interface, not a networking connection.
USB2 makes no sense, as a router sets next to the modem and your systems NETWORKING devices attach to it. If you want to use Internet Connection Sharing(ICS) eg:
modem --- system ---- other system
the other configuration
modem --- router --- systems
is far more flexible and has better performance and control
Fast NAS access is dependent upon lots of factors, but 99.9% of the time, the router is not an issue in performance.
