Best Answer

The maximum speed of USB2 at 480M/Sec is a little quicker than Firewire 400 (IEEE.1394a) which runs at 400 M/Sec (hence the "400" bit of the name). In tests, however, FireWire 400 delivers a higher sustained transfer speed. Benchmarks suggest that hard drives connected with FireWire will copy information considerably faster than they would using USB 2.0. To achieve higher performance, FireWire requires additional circuitry in supported devices. This often makes FireWire more expensive than USB 2.0. Firewire 800 (IEEE.1394b) as the names suggests, has a peak speed of almost 800 M/Sec. Used primarily by PC musicians for recording and transferring multichannel audio at high sample rates and for digital video cameras and decks

Firewire is faster than USB data transfer. FireWire 800 is faster than FireWire 400. USB 3 is faster than USB 2. SATA [& eSATA] is faster than FireWire and USB 3. This is in reference to the data transfer cables between a device and a computer.

What is the difference between USB and FireWire?

FireWire has a higher transfer rate than USB, making it more suitable for video transfer and connecting external storage. USB is host-based, meaningit must have a host computer to transfer data to / from (with a few exceptions). FireWire devices can transfer data between themselves directly without the need for a computer host. FireWire supports fewer devices connected together (63, vs. 127 for USB).

What is the purpose of a firewire port in a computer system?

i am assuming that you know what a firewire is. not all computers come with a firewire input. if your computer doesn't have a firewire IN. then you have to buy a card, which gives you the acessability to plug a firewire cable into your computer.
