Don’t mind that headline. I’m just trying to win the in-house competition for cramming the most incomprehensible tech phrases into one line. Let’s start with the easy bits first – USB key. That means USB drive. Or USB stick. Or, if you’re really confused about tech naming conventions, a memory stick. Just be warned that calling it a “memory stick” makes you sound as stupid as granddad does when he calls your Xbox 360 a “PlayStation.”

So to recap. The PicoDrive ST is a lump of RAM, that comes in up to 8GB size. It’s small so you can put it in your pocket.
