Perhaps not terribly relevant to your question but here's some FW card
vs. onboard test results I posted to this list back in April.
-------------------------------------------
using ATTO's ExpressPro-Tools 2.7 'Benchmark Volume' utility with a LaCie
60GB FW desktop drive (Oxford 911 chipset).
Pismo (9.2.1) onboard FW:
peak read= 20.17 MB/s
sust'd read= 16.76 MB/s
peak write= 14.21 MB/s
sust'd write= 14.16 MB/s
Pismo with FW2Go cardbus card, v1.01 driver:
peak read= 38.51 MB/s
sust'd read= 30.91 MB/s
peak write= 9.99 MB/s
sust'd write = 9.98 MB/s
3400 (9.1) with FW2Go cardbus card
(original non-cardbus cage BTW):
peak read= 1.99 MB/s
sust'd read= 1.721 MB/s
peak write= 7.32 MB/s
sust'd write = 7.27 MB/s
And for reference, here's the same drive on some desktop Macs-
9600/G3 (9.1) w/FW PCI card:
peak read= 30.36 MB/s
sust'd read= 27.20 MB/s
peak write= 23.42 MB/s
sust'd write = 23.34 MB/s
Beige G3/83mhz bus (9.2.1) w/FW/USB PCI card:
peak read= 32.54 MB/s
sust'd read= 30.85 MB/s
peak write= 20.94 MB/s
sust'd write = 20.85 MB/s
The Pismo's onboard FW read performance seems a tad pokey compared with
the FW2Go, but then the FW2Go card had stinky write speeds . . . Wierd
how the 3400's reads were soooooooooo slow.

NewerTech FW2Go cards are available here:

OWC sells a Mac-compatible Century-brand FW cardbus card. At under US$28
that's worth a try too.
