at ioSafe want to make sure you're hooked up with plenty of storage to mark the occasion. As a result, they're hooking you up with three chances to win a Rugged Portable hard drive of the 500GB variety (sorry, Terrence and sledgehammer not included). Half a terabyte of storage capacity ain't too shabby, but the beauty of this prize is not in what it can hold, but rather what it can endure. It's designed to take a heckuva lot of abuse from whatever you throw at it: drops, water, chemicals, you name it. So don't delay, enter to win and celebrate World Backup Day!
