I will be getting the new Mac Mini. It sports an 800 speed firewire. My external HD is 400 speed. I can connect the two with a 6 pin to 9 pin firewire cable. Of course I will lose the advantage of the 800 speed of the Mini. Any advice on whether I should bite the bullet and cough up the dough for an 800 firewire HD? LaCie has a 1T HD on sale for $149 which allows for both 400 and 800 firewire speeds. A novice in these matters, Jim
