NAS & SAN: 2 Types of Network Storage

The two standard types of network storage are network-attached storage (NAS) and a storage area network (SAN).

You use a NAS to provide file-sharing storage to nodes on a LAN over Ethernet. Usually, a NAS server will have a set of drives that provide centralized storage for all users of a network. These servers offer reliable consolidated server storage, and they are relatively inexpensive and easy to both set up and maintain. But they don't offer the best speed or latency.

A SAN, on the other hand, offers shared pools of storage devices to multiple servers and is dedicated to a high-speed network or subnetwork. When using a SAN, each server in the network can access a SAN's drives as if they were locally attached. In essence, it offers the features of a NAS but with better performance. On the down side, though, it is more expensive than NAS servers and is more difficult to set up.
