Hello! I'm planning to buy a WD HDD 500GB or Higher, But I Just find out a difference on the mode That I can't really figured it out. This one: http://www.newegg.com/Product/Product.aspx?Item=N82E16822136073 It cost 109 has the same 7200rpm 16MB cache SATA 3.0 than this one http://www.newegg.com/Product/Product.aspx?Item=N82E16822136143 And this last one cost 144 plus S&H My question is what's the difference between the SE and the RE Version? I see same speed same cache same interface, so are the $40 bucks worth it or the best deal is the first one for 109 with free shipping? The reviews says the SE is a little bit louder and I care a lot about the quietness of a HDD but so far all my HDD from WD are very quiet. So if any of you have some experiences you could share I would really appreciate your input. Thank you very much!
