It seems paradoxical that you'd have to ship cloud data, but plenty of companies do -- it's sometimes faster for them to send a courier than to wait days for a massive upload to finish. And Amazon knows it. The internet giant just revealed the Snowball, an odd but unassuming storage device that shuttles up to 50TB of data to Amazon Web Services the old-fashioned way. The box is not only tough enough to survive the bumps and jostles of a courier, but has everything it needs for power and networking. There's even an E Ink control panel on the side that doubles as an automatic shipping label.
