Abstract: A network storage device. In one embodiment, the network storage device of the present invention uses solid-state non-volatile memory (e.g., flash-memory) as a storage medium, and has at least one interface configured for coupling to a computer network. The network storage device of the present invention is accessible to client(s) and/or server(s) of the computer network, and uses solid-state non-volatile memory to store data received therefrom. The network storage device may also be configured to include a memory for caching data to be written to the solid-state non-volatile memory. In order to provide additional storage, the network storage device may also include a peripheral interface or another network interface for coupling to a mass storage device (e.g., a RAID system), and/or another network interface for coupling to a network of mass storage devices. The network storage device may be a stand-alone unit, or may be implemented as part of a network server, or as part of a mass storage device.
