I can get can a Lacie 320 GB quad-interface portable hdd for 170, or the 500 gb verson for 220. The 500GB gtech fw 400/800 is like 270 bucks and the 320 GB quad interface is 240 bucks. Why? Anything better about them? Does anyone know about either of these drives? I want something fast, sleek, good for hd video, and maybe on the slim side. (They all need to be firewire 800) Which one fits the best on a desk next to a new 24" iMac? How slim are they? I have a 260 dollar gift certificate to the apple store, so money is not an issue, just looking for the most bang for my buck.
