A network attached storage NAS and storage area network SAN are 2 methods of allowing access to information over a standard Ethernet network. Operating either a NAS or SAN is vital for the integrity of the data stored on the drives found in the device. Redundant array of independent disks RAID configurations are possible with such a device and allow for data backup in case of drive failure as well as increased capacity beyond a single disk. Differing RAID configurations and different types of disks help determine the speed of the system as much as the speed of the network itself. Many standards are in place for transferring data, including more standard ones such as File Transfer Protocol and Server Message Block, and newer standards such as Internet Small Computer Systems Interface. The differences in the protocols also play an important role in determining the most effective setup for a NAS to SAN.
