I Was wrong about mixing FW800 and FW400 hard drive on the same bus

I was wrong in what I’ve said on this post. I tested this with a FW400 iSight external camera and my results for that are right. However today I restested this using two external hard drives (one FW400 and one FW800). I did no have any data rate loss at all. I will put out and updated screencast showing this. My apologies for the bad information. However if you are using a FW400 camera of some type I would check that because my test with the FW400 iSight did degrade the bus.

    I like your show! Great as always.
    Good information about FireWire. Currently I use Lacie FW400 DVD burner with my FW800 drive that are plugged into my Mac Pro. I haven't noticed the degradation, but I think I will run the test, just to be sure.
    It seems that the iSight camera or perhaps other FW400 peripherals can slow down the bus.

    Yes do it yourself because as I said I tried this without the Apple camera and did not see the degradation.
