Network Attached Storage
Network-attached storage (NAS) is a computer data storage device that is connected to a computer network providing data access to an assorted group of computers. NAS not only operates as a file server, but it is specialized for this task because of hardware or software. NAS are often manufactured as a computer add-on and built from the ground up for storing and sharing files on computers on the same network.
Since 2010, NAS devices are growing in popularity both as a convenient method of sharing files and storing data. Potential benefits of network-attached storage, compared to file servers, include faster data access, easier administration, and simple configuration.
NAS systems are networked HDD’s, often arranged into logical, redundant storage containers or RAIDs such as RAID 5. Network-attached storage removes the responsibility of peer-to-peer file serving on the network. They typically provide access to files using network file sharing protocols such as NFS, SMB/CIFS, or AFP.
These units are in essence a computer connected to a network that provides file-based data storage and services to other devices on the network. For example, an NAS unit usually does not have a keyboard, display, and are controlled and configured over the network, often using an inter-net browser.
NAS uses file-based protocols such as NFS (popular on UNIX systems), SMB/CIFS (Server Message Block/Common Internet File System) NAS units rarely limit clients to a single protocol.
