Apple's Thunder bolt...

Thunderbolt is a revolutionary I/O technology that supports high-resolution displays andhigh-performance data devices through a single, compact port. It sets new standards for speed, flexibility, and simplicity. And it’s on MacBook Air, MacBook Pro, iMac, and Mac mini.

Powerful technology from a powerful collaboration.

Thunderbolt began at Intel Labs with a simple concept: create an incredibly fast input/output technology that just about anything can plug into. After close technical collaboration between Intel and Apple, Thunderbolt emerged from the lab to make its appearance in Mac computers.

Intel co-invented USB and PCI Express, which have become widely adopted technologies for data transfer. Apple invented FireWire and was instrumental in popularizing USB. Their collective experience has made Thunderbolt the most powerful, most flexible I/O technology ever in a personal computer

.

Performance and expansion made faster and smarter.

Thunderbolt I/O technology gives you two channels on the same connector with 10 Gbps of throughput in both directions. That makes Thunderbolt ultrafast and ultraflexible. You can move data to and from peripherals up to 20 times faster than with USB 2.0 and up to 12 times faster than with FireWire 800. You also have more than enough bandwidth to daisy-chain multiple high-speed devices without using a hub or switch. For example, you can connect several high-performance external disks, a video capture device, and even a display to a single Thunderbolt chain while maintaining maximum throughput.
