I have several Iomega USB ones which I use for storage, and are nice and portable. My first was about 160Gb and the latest one I bought was a hefty 750Gb. I'm pretty sure they do Tb ones now, and I've got to go out in a mo but when I get back later I'll try looking out some links for you. My only caveat would be that they do run fairly hot, but I don't leave them running for any length of time - just power them up when I need them.

In the meantime, I have dragons' eggs and hatchlings that all need lots of clicks to help them hatch and grow - please help?
