That Powercore Firewire looks like a perfect addition to my iBook/828 rig. My only concern is how well the single Firewire bus on my iBook will handle an 828, a Firewire hard drive, and a Powercore running all at once. I know that several 828's are supposed to be able to run on a single Firewire bus with no problem, so that means there is quite a bit of bandwidth to spare, but I'm not sure how much my hard drive eats up at, say, 16 tracks of 24bit/44.1. Does anyone have any information on the bandwidth usage of the Powercore Firewire? Thanks...
