I've heard good things about the WD drives and I want to make sure this is the right one: http://www.bestbuy.com/site/olspage.jsp?skuId=9172799&type=product&id=1218044489855 I understand I can get it cheaper online but I'm impatient and would rather walk in today and grab one I have an early 2009 base 15" Macbook Pro. Would this drive suit me well? I'm looking to split between OS X and Windows. I do development in Windows so I'm a little concerned that I should be going for a 7200 rpm drive instead. What do you think? Thanks.
