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?
