NAS Adapter

Discontinued and replaced by NAS40ESU


The Addonics NAS Adapter is a convenient and economical solution for adding any USB storage devices onto your LAN (Local Area Network). Once on the network, the USB storage can be shared by any network user, just like an ordinary NAS device. When used in conjunction with Addonics Storage Towers or Storage Racks, a Multi-Tera bytes storage with various RAID capabilities can be instantly added to the LAN. With the NAS adapter, you can custom build you own NAS appliance with RAID capability and plenty of storage expansion using Addonics family of Drive Enclosures, Port Multipliers, and IO converters.

Coming with a built-in USB 2.0/1.1 connection and a fast Ethernet 10/100Mbps connection, the NAS adapter supports both SMB (Server Message Block) and the open source Samba network protocols, allowing for cross-platform access of all shared data for most versions of Windows, Mac OS X, and various Linux distributions. For remote users who are not connected over the LAN, the NAS Adapter provides FTP access for up to 8 simultaneous users anywhere in the world with an internet connection. In addition, the NAS adapter can also be used as a print server or as a Bit-Torrent downloading appliance.
