Hmm, that's odd. I could've sworn that model iBook has USB2.. (?) In my experience (I've never recorded music with more than 8-10 tracks), my ability to record/playback is not limited by the data rate to the hard disk (whether I use USB2 or FW), but rather is limited by the internal bandwidth in my iBook. Granted, yours will be at around 50% faster than mine, but I suspect your limiting factor will be your iBook's ability to shunt/process data internally - regardless of the HD you use. I guess the problem of daisy-chaining your soundcard to an external FW hard disk is audio latency, so that's a no go. One thing you should do then is go to a forum for semi-pro/pro musos, and talk to them about the likely benefit you'll see from upgrading your internal HD. It's gonna cost you several hundred dollars, and you want to be sure it's worth it!! ;-) Good luck, and have fun! Cheers, -Angus ps. When you do sort something out, can you let me know how it works? I'd be interested! ;-) Quoting Steve H Jones <shjones at hywyn.plus.com>: > > G'day, > > > > Have you considered an external hard disk?
