ext2 is problematic for removable drives because if you remove the drive
without cleanly unmounting it you risk losing your data. So I would
recommend ext3 for such uses. Performance is rarely an issue, actually.
I use ext3 for my external USB drive. Does this mean that I can remove
it without cleanly unmounting it and not need to worry, or do you
merely mean that I'd be less likely to lose data than if I'd use ext2?

I think it is not quite so robust as that. From reading wikipedia, I
think fsck can clean up the mess, faster and more reliably if journal
is available. I think. I'm not sure. But surely your better off with
journaling than without when you accidentally pull the plug too
soon. And one thing I know for sure about me. I make mistakes.
Does anyone here power off their computer without first shutting it
down? Maybe, but after having to spend time repairing the system and/or
rebuilding it or losing data they most likely don't anymore.
Lose one's data a few times after removing the drive without unmounting
it will change one's behavior to checking before unplugging.
Neither ext2 nor ext3 were designed to be used in this manor. Even with
it superior recovery system ext3 can still suffer from total data loss
if used in this manor.
