USB drives and ethernet drives do not have the sustained throughput necessary for editng, especially ProRes, without dropping frames. Firewire 400 is minimal, firewire 800 is good, a single SATA is real good, and stripped SATA raid is even better.
Get yourself the free Videospace widget from http://www.Digitalheaven.com and you’ll never have to ask anyone about how much drive space is taken up by a certain codec again. Just select the Quicktime codec you want to know about in the dropdown menu in Videospace, type in the running time, and presto, it calculates the hard drive space for you.
