Well, the portables are built for easier transport and such; light and durable. Lower power needs, lower operating temperatures, slower disk rotational speeds (typically @ 5400 rpm), smaller physical size of some components, etc., which some consider more suitable, overall, for backup and storage usages.
All of my own externals are LaCie desktop models @ 7200 rpm, each with its own DC power supply transformer to deal with, but I'm very satisfied with them overall. In fact, I use the small one (80GB) as my primary boot volume instead of the internal which is a 5400 rpm drive; l use the internal as a clone backup, and also as a boot volume for certain maintenance tasks.
