well this was originally was a question dealing with a PCI-to-Firewire card, but i got to thinking. if i'm not mistaken, the PCI slot has a transfer rate of 133 or so Mb per second for each slot. i thought i saw a company that advertised firewire PCI card for PC's, advertised with a xfer rate of 400Mb/sec. how can this be? the PCI would bottleneck this to 133, correct? which leads me to PCI SCSI interfaces: would an ultra160 SCSI be capped off at 133 as well?

You are getting two thing mixed up here..Megahrtz vs Megabits...
You are getting two thing mixed up here..Megahrtz vs Megabits...PCI bus has a certain reference speed..how many calculations per second..Firewire has a data stream..how much information per second..Fire wire can handle 400Megabits per second..roughly 50MB a second..PCI bus can handle that very well especially if you have a 133front side bus...133 Million calculations per second at 32bit..pretty snazy if you ask me!!! Even 100Mhz bus speed is good too!!
Hope that clears things up for ya
