I bought a 750GB Seagate drive with SATA interface. I need to get an external enclosure for it that has internal SATA; but is USB 2.0 good enough? I'm thinking of hooking up to to my Airport Extreme Base Station to wirelessly share the whole drive and then setting up movies and music to it. Just concerned that USB isn't good enough. FW800 is obviously the best way to go - but I won't be able to share it wirelessly. http://www.newegg.com/Product/Product.aspx?Item=N82E16817198004 This is one I was looking at..
