There are very little advantages to this but I belive that if you install a game to your hard drive your xbox will run a little cooler and if your disc shatters or breaks inside the xbox 360 itself then your data from your games is not lost and can be retrieved from your hard drive. Hope this helped.
A fire wire external hard drive can help your computer to run very quickly since the power from within is very strong. The external hard drive always allows easy access to any problems and allows tons of data to be stored.
