Network attached storage, or NAS, is a practical choice for anyone needing digital storage, both at the workplace or in the home. NAS offers a versatile means of storing data, and is categorised as a file-level storage architecture, one of the three main storage types along with storage area networks (SAN) and direct-attached storage (DAS). NAS offers the key benefit of making any data stored on it more available to other devices connected to its network, thereby allowing the device to act as a single point of storage for a network, with effective security, management, and fault tolerant capabilities all built in.
