Thunderbolt I/O

The new MacBook Air supports Thunderbolt I/O. Apple worked with Intel to come up with Thunderbolt I/O for their computer systems. Thunderbolt I/O is a combination of PCI Express and DisplayPort technology. Fast transfer uses such as with RAID arrays and video capture will benefit from the Thunderbolt I/O connection. Thunderbolt also provides 10 watts of power to external devices. Using adapters, you can also connect USB, FireWire, Gigabit Ethernet, and Fibre Channel networks with the Thunderbolt I/O port.

The performance of Thunderbolt I/O is 10 Gigabytes per second (Gbps) data transfer rate. USB 2.0 ports provide 480 Megabytes per second (Mbps), and USB 3.0 ports provide 5 Gbps transfer rates. Data writing with Thunderbolt is 746 Mbps, while reading is 864 Mbps. FireWire has only 77 Mbps writing speeds, and 93 Mbps read speeds. USB 2.0 has 28 Mbps writing speed and 41 Mbps reading speeds.

You can connect up to six peripherals with the Thunderbolt port. The way this is accomplished is with a daisy chain configuration. This will also connect the MacBook Air up to their large 27-inch Thunderbolt Display.
