The new Intel technology called
Thunderbolt is making the headlines nowadays.
With some already calling it a USB killer, Thunderbolt can gain transfer speeds of up to 20 times faster than USB 2.0.
From Intel: With the 10 Gbps performance of Thunderbolt products you can transfer a full-length HD movie in less than 30 seconds, or backup 1 year of continuous MP3 playback in just over 10 minutes.
While the newest USB 3.0 connection maxes out at around 4Gbps (400MBps), Thunderbolt will push over 50% more than that (in a realistic environment).
Unfortunately the technology won't be available anytime soon, definitely not in time of my next PC purchase this year... damn.
