The good people at MobileMag got a chance to review the new Addonics pocket NAS 2.0 NAS2XU2, and they report that for the price and the size, it's worthy of your attention.
You guys showed some interest when we got our first look at the NAS2XU2 back in November, and MobileMag reports that by and large it lives up to its promise. The pocketable device sports 2 USB ports and now has gigabit ethernet, improving the slow transfer speeds that plagued the first model.
MobileMag had some trouble getting the built-in media sharing system to work, but the unit supports SMB and Samba so with some tinkering it will likely do fine as a media server. As a mini FTP server, a hub for USB devices, and Bit Torrent server, however, it worked like a charm.
