A NAS device is a storage device connected to a network that allows storage and retrieval of data from a central location for authorized network users and varied clients. NAS devices are flexible and scale-out, meaning that as you need additional storage, you can add to what you have. NAS is like having a private cloud in the office. It’s faster, less expensive, and provides all the benefits of a public cloud on-site, giving you complete control.
