Since I'm borderline retarded when it comes to computer crap, I figured I'd ask people who know far more than I do the following question:
I'm interested in buying an external hard drive. After looking around at my choices, I'm even more clueless than I was before. Any suggestions?
C'mon people...help a moron out.

One other thing you might see advertised is the size of the disk cache - usually 8mb these days; you might see some go up to 16mb or some older ones with 2mb. More is better, but the performance gain will be pretty miniscule and I doubt you'd notice it much even if you had two otherwise-identical units side by side.
You'll also see seek times - that's the average time it takes for the hard drive to find and begin reading from or writing to a specific spot on the physical disk surface. This probably isn't really going to be all that important to you. It's mostly for people way up higher on the price/performance curve who're willing to spend extra bucks to make Windows boot three seconds faster, or cut load times for on-disk databases by a crucial 0.2 seconds.
