Need an external hard drive?

I am running out of space. Not in my home, in my computer. I have backed up most of mys stuff but my hard drive is filling with recent stuff that I need to keep.

What do I do? I am thinking of looking at getting an external hard drive to solve the problem. This way I could easily store data and probably get a big enough one to keep a 2nd backup of important data.

I will probably look at getting it from somewhere like Buy.com.
