Hi, I occasionally do light video editing on my macbook pro, and I stream videos to my xbox in another rooom. I need more space than my internal 5400 rpm 160GB HD. I can either get an internal, or an external. I don't move my computer at all, so an external would be just fine. If it doesn't require a power outlet, even better. So my question is.. what kind of HD should I get? eSATA, FW800, USB 2.0? Should I buy the HD, and enclosure seperate? Should I buy something already assembled like the WD Mybook? I've had a few HD + enclosures that I had assembled. I liked them, except for the fact that they were a bit loud. Not sure if it was the enclosure making all the noise, or the HD.
