Wow, Intel demoed a wired protocol called Light Peak recently and it's blistering fast. Its fast enough to transfer and entire blu-ray movie is 30 seconds.
Not sure if it will make it to mainstream PC's because it seems that Apple is behind the curtain pulling the strings. Intel expects to have it in Apple computers sometime in 2010.
USB 2.0 has an average transfer rate of about 350 megabits
Firewire 800 has an average transfer speed of 750 megabits
Light Peak has a demonstrated transfer speed of 10 gigabits, and theoretical capabilities of 100 gigbits. :shock:
