NAS Devices

A network-attached storage (NAS) device is a data storage device that connects to and is accessed through a network, instead of connecting directly to a computer. The NAS device contains a processor and operating system, so it can run applications and provide the intelligence to share files easily with authorized users. 

A NAS device's great advantage is being able to be accessed by multiple people, multiple computers, mobile devices, or remotely (if properly configured).
