Firewire is twice as fast as usb 1.1, but not as fast as usb 2.0

There is a new firewire slowly starting to appear that will
be about twice as fast as existing usb 2.0 (or existing firewire)
but I've not actually seen this in production yet.
AFAIK, Firewire 2, 800Mbps does exist for years. Maybe it's becomming
mainstream now. Or maybe there are few devices using it.

It is often called FW-800 and it has been around a couple of years.
There are many devices using it. The first FW is called FW-400.

BTW, FW-400 is typically faster than USB 2.0 in many uses. Especially
streaming images. On our FW-400 system, we actually get 400 MBit of data
(calculated with cameras that provide an uncompressed image size/rate).
I am not sure if the USB 2.0 speed is for the data only, or it if
includes the transmission overhead.
