At 400 megabits per second, the FireWire/1394/i.LINK standard is ideal for multi- media input devices such as digital video (DV) camcorders, and high-speed storage devices, scanners, and CD-RW drives. In fact, you can "daisy chain" up to 62 peripherals from the two external FireWire ports on your DuoConnect card. USB 2.0 combines high-speed performance with the plug-and-play simplicity that has made USB peripherals so popular. USB 2.0 products include external hard drives, CD- RWs, DVD-Rs, and scanners can run at up to 480 Mbps. That's 40 times faster than USB 1.1 peripherals. DuoConnect's three external ports provide maximum compatibility and connectivity to the newest USB 2.0 devices as well as USB 1.1 devices.
