Router USB ports can create networked file servers for connected devices
Tech outlets report that the unused USB port on many home Wi-Fi routers can be configured to turn an external drive into a shared network storage device.

Setting up shared storage access
Users must enable specific settings like File sharing or Media sharing within their router configuration. Once activated, the system allows any connected device to reach the plugged-in hard drive or SSD. Access methods include SMB, Samba, or FTP depending on the chosen protocol.
Hardware requirements and capabilities
The port works with external hard drives, solid state drives, and flash drives attached to the back of the unit. Newer router models offer faster USB 3.x connections that provide more performance headroom for these tasks. Exact features vary by manufacturer and specific model design.
