An external hard drive is usually USB, so basically it's just a really big USB drive.

Pros of an external hard drive are the capacity.

Cons are they're physically larger so some of them just won't fit in your pocket like a thumb drive. The only other con I can think of is that most of the larger external hard drives require an external power source.
