Diferença entre USB e FIREWIRE

Quais as diferenças entre as portas USB e FIREWIRE ?

Se alguém por acaso souber... x]

USB 2.0 é mais rápido que FIREWIRE.

Outra diferença é o plug

Me corrijam se estiver enganado, mas já ouvi falar que a fireware é bem mais rápida que a USB, apenas não "pegou" muito nos equipamentos. Não é isso?

Acho que isto só e verdade se comparado a USB 1.1, mas sei lá quem manja do assunto que venha dar a Luz aos incáutos.:whistle:

A velocidade anda mais ou menos igual de um para outro,o firewire é mais usado em maquinas de video digital, e o usb2 é mais universal.

Firewire é bastante usado para conectar filmadoras digitais no PC.

FireWire vs. USB 2.0
Question: Which is faster Hi-Speed USB 2.0 or FireWire?
Answer: In sustained throughput FireWire is faster than USB 2.0.

Question: If Hi-Speed USB 2.0 is a 480 Mbps interface and FireWire is a 400 Mbps interface, how can FireWire be faster?
Answer: Differences in the architecture of the two interfaces have a huge impact on the sustained throughput.


FireWire vs. USB 2.0 - Architecture
FireWire, uses a "Peer-to-Peer" architecture in which the peripherals are intelligent and can negotiate bus conflicts to determine which device can best control a data transfer


Hi-Speed USB 2.0 uses a "Master-Slave" architecture in which the computer handles all arbitration functions and dictates data flow to, from and between the attached peripherals (adding additional system overhead and resulting in slower data flow control)

FireWire vs. USB 2.0 Hard Drive Performance Comparison
Read and write tests to the same IDE hard drive connected using FireWire and then Hi-Speed USB 2.0 show:

Read Test:
5000 files (300 MB total) FireWire was 33% faster than USB 2.0
160 files (650MB total) FireWire was 70% faster than USB 2.0

Write Test:
5000 files (300 MB total) FireWire was 16% faster than USB 2.0
160 files (650MB total) FireWire was 48% faster than USB 2.0

Question: So which products should I choose FireWire or Hi-Speed USB 2.0?
Answer: Often the choice will be made for you by the product itself. Some types of products are only available with the FireWire interface and some only with USB.

For all out sustained throughput, as shown above a FireWire external hard drive will provide the best performance. But for convenience and compatibility between multiple computers a USB 2.0 external hard drive would probably be the better choice (since practically every computer has a USB port).

Better yet, get both interfaces. We offer combo FireWire USB 2.0 cards allowing you to connect products with either interface to your computer. And a combo FireWire USB 2.0 External drive gives you best of both worlds...you can have the highest hard drive speed when connected to a FireWire port, and also the broad compatibility of USB.

One product category that USB currently has an advantage in is capturing video tape for DVD. Using hardware MPEG encoders, USB video capture products are able to convert VHS to DVD video.

Existem 2 tipos de conexao Firewire. O Firewire 400 eh BEM mais rapido que USB 1.1 e em testes fica praticamente igualada a 1 conexao USB 2.0.

Mas ja existe o Firewire 800, que supera com folga a conexao USB 2.0. Abaixo segue 1 grafico e 1 link do site da Apple explicando a diferenca das conexoes.
