I want something that is cool, fast, and quiet....and something that won't break in 8 months (although it seems there's at least 2 reviews for each product with someone saying that the hard drive broke within a year). I have read hundreds of reviews of each product -- they all seem like great products, but I am having trouble deciding. Feel free to suggest alternatives. I prefer not to go to the 7200rpm route since I want something cool and quiet.
