Corsair is very much associated with devices that need a physical connection to work, whether they're thumb drives or memory sticks. It's looking to cut the cord in style through its new Voyager Air. You'll have seen some of what it does with a predecessor like Kingston's Wi-Drive, with media streaming to Android and iOS devices, a WiFi repeater mode and USB 3.0 support, but Corsair's drive goes the extra mile by serving as network attached storage through a gigabit Ethernet link. The 7-hour battery life when completely wireless certainly helps its prospects, at least among its immediate rivals. Corsair plans to ship the Voyager Air by early February in a 500GB version for $199 and 1TB for $229 versions; either price sounds reasonable for a home media server that ultimately doesn't have to stay at home.
