Network Attached Storage
NAS drives - Network drives
Network-attached storage (NAS) is file-level computer data storage connected to a computer network providing data access to a heterogeneous group of clients. NAS not only operates as a file server, but is specialized for this task either by its hardware, software, or configuration of those elements. NAS is often manufactured as a computer appliance - a specialized computer built from the ground up for storing and serving files - rather than simply a general purpose computer being used for the role.
As of 2010 NAS devices are gaining popularity, as a convenient method of sharing files among multiple computers.
Benefits of network-attached storage, compared to file servers, include:
NAS systems are networked appliances which contain one or more hard drives, often arranged into logical, redundant storage containers or RAID. Network-attached storage removes the responsibility of file serving from other servers on the network. They typically provide access to files using network file sharing protocols such as NFS, SMB/CIFS, or AFP.
