You would need some sort of NAS device to act as a file server (you obviously can't just plug a HDD directly into a switch). Some consumer routers have USB ports where you can plug in an external HDD, though they frequently have speed issues with the USB ports. You could buy something from QNAP, Synology, etc. or build your own TrueNAS.
