How does USB compare to IEEE-1394?
The two serial buses seem similar, but they are intended to fulfill different bandwidth and cost needs. IEEE-1394 can move more data in a given amount of time, but is considerably more expensive than USB. IEEE-1394 is best suited for disk drives, high quality video streams and other high bandwidth applications. USB is appropriate for middle and low bandwidth applications such as audio, scanners, printers, keyboards, and mice. For more info on IEEE-1394, see our Firewire FAQ page.
