There are definitely distros which will run faster than Ubuntu.
Have you looked at the newly resurected Slax
Slax is based on Slackware and is desgned to be a portable Linux install to a usb drive. See their documentation: http://www.slax.org/en/documentation.php
There is also Pendrive Linux
for installing Linux distros to a flash drive. http://www.pendrivelinux.com/
Installing a Linux distro to an external usb connected hard drive should be much the same as installing to an internal hard drive.
Just be sure that the grub bootloader is installed to the MBR of the usb hard drive and not the internal hard drive.
Then you can set your computer's BIOS to boot from the usb connected hard drive as the first boot device, and the internal hard drive as the second boot device. This way, if you have the external hard drive connected it will boot from that first. If you do not have the usb hard drive connected the computer will then boot from the internal hard drive.
