Beyond the scope but if you are doing non-music stuff that requires moving files quickly you're more likely to be limited by the storage subsystems on either end. It's pretty hard to saturate even 1gb Ethernet with spinning rust drives. Generally in the home the key for large file transfers is just to do it while you're doing something else so you're not waiting (or at a time you aren't even there). If you need a serious business network for
actual work you can use professional networking hardware that can be acquired affordably on the used market; I'd point you down the rabbit hole of
ServeTheHome (that link and the rest of that forum.)
