Hi Chris,<br />
I've been able to consistently observe differences in transfer speeds between Firewire and USB 2.0, with Firewire 400 being faster. I know this is attributable to real world bandwidth and perhaps latency differences, but it may also be indicative of architectural differences intrinsic between the two interface specifications. Differences like the fact that USB host incurs most of the overhead associated with the transfer, and that perhaps other factors that I can't substantiate but have heard about Firewire; that more of its implementation is "on-chip" (for lack of a better term) vs USB for example.<br />
Whether this amounts to measurably less jitter is arguable, but it seems very plausible.<br />
Any feedback you can provide is appreciated. Thanks.
