When and Why to Use Network-Attached Storage
 

One of the most powerful tools for data storage is a Network-Attached Storage (NAS) device. A NAS device is any product which connects to a network in order to provide file access to the network's systems. A NAS device generally has on-board hardware aside from the hard drives which control the file storage and distribution, it can even have its own operating system. NAS products range from things as basic as external hard drive enclosures which are attached to a router to large, multi-drive devices which house a controllable operating system, a switch, and other useful accessories.
