LaCie XtremKey: One of those extreme can-take-it-all USB keys that you can run over, boil, roast in the oven, drop in water, freeze, and sledgehammer—then eat it and poop it out. According to the video, it'll keep working.
The LaCie XtremKey can work 333 feet underwater. Its temperature operating range goes from -58ºF to 392ºF, and it can transfer data at 40Mb/s. The USB key is made of zamac, "a metal alloy composed of zinc, aluminum, magnesium and copper that's so strong, it can withstand the pressure of a 10-ton truck." With a name like zamac, nothing can go wrong unless Ultron steals it or buys it for $50.
