Hi John;
Go to Wikipedia FireWire.
http://en.wikipedia.org/wiki/IEEE_1394_interface
and scroll down towards the bottom and read the section "Comparison
with USB".
The other issue is that when you begin running multiple IIDC Cameras,
firewire really begins showing how much more efficient it is,
especially since the transfers of data are all DMA and don't involve
the CPU to do it.
As soon as you cross over to FireWire 800, USB2 looks positively anemic.
HTH..

Hi all,
I responded to a new imager about the pros and cons of firewire vs
usb cameras for solar imaging on another list. I remember Milton
responding saying that despite the similar bandwith specs the
transfer rate is superior with the firewire protocol. Having both
ports available, I suggested the FW cam.
I searched the list but did not turn up Milton's post (sorry
Milton... I know search is a sore spot 8^) . I was wondering if my
memory is correct and if so, can anyone direct me to the post so I
might relay this information. Of course if I am off base on this I
would like to stand corrected as well.
Thanks in advance,
John
