floppy disk

A very simple portable storage device. It's probably among the best choices for use on sneakernet because it's easy to write to and requires no special software. It's far faster to write to a floppy than to burn a CD, and it's kind of a waste to put a few documents on a CD. Plus you can edit files on a floppy without having to re-burn. They are slowly being replaced by USB drives, but they have at least a few years ahead before they are officially obsolete. Floppies are far more durable than most of those Linux geeks say they are, as long as you don't dip them in bleach or something. You can drag your keys all across the outside of a floppy and it'll still work fine. Try THAT with a CD. They hold 1.44 megabytes with standard formatting and are about 3.5 inches square.
