Firewire external IS faster than your laptop drive any day, any time, any place, and in any way. You WILL see it for yourself when you WILL run game from laptop drive and then do the same from Firewire.
..this is very useful and helpful place for information...
Yes, this time I can agree! A fast drive should keep the Firewire's 50MB/s bandwidth filled most of the time. While that's a limitting factor, it's not nearly as bad as the fact many 5400RPM hard drives have difficulting maintaining 33MB/s, even if they're rated "ATA100"!
