I am looking to get a quiet and cool 7200 RPM 500 gig hard drive got my uMBP 2.53. After using SEARCH! and reading through some post it looks like most people are going with the Seagate Momentus 7200.4 500 gig. I am impatient and found the drive for a decent price at Best Buy....but I see no mention of the 7200.4. Is this the same drive? http://www.bestbuy.com/site/olspage...s+500&lp=1&type=product&cp=1&id=1218085426687 Thanks!!
