I read the PC Magazine sometimes. One term is coming often and often. It is Thunderbolt.
It is a new standard for I/O device of computer.
Thunderbolt (codenamed Light Peak) is a hardware interface that allows for the connection of external peripherals to a computer. It uses the same connector as Mini DisplayPort (MDP). It was released in its finished state on February 24, 2011.
Compared with other ports of PC, the speed of I/O is much more fast. See below.
USB 3.0 is a fast speed connection between PC and portable disk. But the Intel said Thunderbolt can provide double speed of USB 3.0. It is not enough. 10Gbps is just one way. Thunderbolt can do same speed at the both directions. So max total is 20Gbps.
