Network-attached storage (NAS)
Network-attached storage (NAS) is data storage or a data storage device, such as a hard drive or RAID array, connected to a computer network, providing data access to different network clients.
NAS systems contain one or more hard disks, often arranged into logical, redundant storage containers or RAID arrays (redundant arrays of inexpensive/independent disks). NAS devices remove the responsibility of file serving from other servers on the network.
NAS provides both storage and file systems. This is often contrasted with SAN (Storage Area Network) devices, which provide only block-based storage and leaves filesystem concerns on the "client" side. SAN protocols include SCSI, Fibre Channel, iSCSI, ATA over Ethernet, or HyperSCSI.
Newegg has Network storage / NAS from the world’s best Network storage / NAS manufacturers, including Buffalo, Cavalry, D-Link, Hammer Storage, Intel, iomega, LaCie, Linksys, Maxtor, Netgear, QNAP, Thecus, Western Digital and Synology.
