What determines the transfer rate of Firewire 400?

Question

I read this in Winipedia:

"FireWire 400 can transfer data between devices at 100, 200, or 400 Mbit/s data rates (actually 98.304, 196.608, or 393.216 Mbit/s, but commonly referred to as S100, S200, and S400). Although USB2 claims to be capable of higher speeds (480Mbit/s), FireWire is, in practice, faster due to its "peer-to-peer" architecture which gives a more reliable and sustained throughput rate".

What determines which rate (100, 200, or 400 Mbit/s) the Firewire 400 will transfer at?

Answer 1

Hey, as it says, 400.

when you connect a device compatible with firewire 400, its workin on dat speed.
but if you hooked up a device slower than that, it'll work on that device's maximum speed.
also if you want to connect a device with firewire800, there are sveral adapters from hardware companies to connect a firewire 800 device in to firewire 400 socket.
