The external drive costs a lot less in terms of dollars per space on the drive and stays permenantly attached to your drive and gets t he backup done without intervention from you.
I will add to the list of negatives
Flash drives (Jump drives) are Snail SLOW when compared to a standard rotating drive (even if it is in a USB caddy that runs at USB 2.0 speeds).
It took hours to (Calibre) "copy to Library" my 1200 books to a 2G Flash drive.
I can see the attraction for Flash drives. They are cheap (out of pocket) for 2-4 G sizes (US$ 7-18). That still does not make them (or CD/DVD) good longish term archival media.
