NAS hubs are usually self-contained and, aside from the initial set-up, don't require a separate computer to work, just a network and/or an active internet connection.

It's like a small computer dedicated to storage, streaming and data sharing, and it's usually a faster way to move files between devices than using external drives.

At its most basic, a NAS hub is a central file storage unit that connects to your computer devices in your home via a local network.
