Network-attached storage (NAS) is data storage or perhaps a data storage device, like a hard disk or RAID array, attached to some type of computer network, supplying data use of different network clients.
NAS systems contain a number of hard drives, frequently arranged into logical, redundant canisters or RAID arrays (redundant arrays of affordable/independent disks). NAS products remove down to file serving using their company servers on the network.
Bestselling 1TB Network Attached Storage (NAS) on Amazon.com:
Seagate BlackArmor NAS 110 1TB Network Attached Storage
(MPN: ST310005MNA10G-RK, Price: $199.99, Amazon.com Price: $149.99)
Review: “A little slower than I hoped. ~40MBps read and ~22MBps write – Sequential. Since the 1Gb ethernet spec can go up to 125MBps theoretical I was hoping it would be in the 80-100MBps range. Encryption requires a USB drive plugged in the front. Just fine if you have a small, old USB flash. The backup software is not the most reliable in recovery, but you get 5 free licenses and for Windows XP it is better than built-in. Use Windows 7’s built-in back up with drive.”

NAS provides both storage and file systems. This really is frequently compared with SAN (Storage Space Network) products, which offer only block-based storage leaving filesystem concerns about the “client” side. SAN methods include SCSI, Fibre Funnel, iSCSI, ATA over Ethernet, or HyperSCSI.
