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...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
