Jax2 - I don't really have feel for the disk space required by new OS since I installed it not so long ago.
As for Firewire, I did not intend to give, as you call it, "lesson" on network protocols (I'm hardware guy) but rather point out the main difference that might affect computer operation. In my system, for instance, heavy usage of computer's processor might impede on USB transfers but won't make any difference to Firewire transfers. I also like the fact that Firewire is a daisy chain thing and doesn't require hubs or multiple connectors and cables coming from computer. My three external drives connect to each other and only one wire comes to computer. This is not a "lesson" - I just stated what I like (and YES I think you're worthy - feel better).
