FireWire 800 (IEEE 1394b) effectively doubles the bandwidth of FireWire to 800Mbps over copper. The computer or the device can be on or off when you plug things in. Plug any IEEE device into the computer at any time.
An external scanner or disk drive may also use the IEEE port. On a PC, the IEEE port (called FireWire) is used primarily for connecting audio or video devices to the console. In real world use FireWire 400 outperforms USB 2.0 in bandwidth intensive applications. Your Computer’s FireWire (IEEE 1394) Connections. FireWire allows connections of up to 63 devices, is "hot pluggable," easy to use, and doesn't suffer from the latency and CPU burden issues exhibited by USB 2.0. FireWire provides performance for high-bandwidth applications including mass storage devices like hard drives. Used by most DV25, DV50 and other DV Camcorders, FireWire's ability to guarantee bandwidth and isosynchronous mode makes it a favorite connectivity standard among video professionals. One of the fastest and most versatile bus standards ever devised, FireWire (aka i.LINK and IEEE 1394) makes a powerful addition to any computer.
PCI Express (PCIe) to FireWire host adapters allow addition of FireWire to PCI Express (PCIe) equipped desktop computers. PCI Express to FireWire IEEE 1394 Host Adapter Home
