These Iomega Silver Series hard drives come in both 80 and 120GB sizes, and feature USB 2.0 and Firewire connections to your computer. They can be used in both Windows and OS X, and weigh less than six ounces. They're about $1.65 a gigabyte, and are mainly used to carry data with you on the go.
One use we can think of is to place all your important files, liketax informationtax information, music, work documents, on this drive, instead of on your actual laptop or desktop hard drive. That way, when the cops come snooping around because your kids/wife haven't shown up to school/work lately, you can high-tail it out of town quickly. No muss, no fuss. – Jason Chen
