Two basic and fairly unrelated questions: Before FW800 arrived, I was under the impression that hard drive speeds were so slow in comparison to the rest of a computer's bus speeds that any given external FW drive only uses a fraction of FW 400's available bandwidth. With the advent of FW 800 drives, am I to assume that my previous assumption is false? Second, can a user upgrade the latest eMac's Ultra ATA HD? As in, swap the anemic 40GB drive out of the low end model and replace it with a larger Ultra ATA drive? Thanks for your help!
