Friends, Apple doesn't offer a 7200RPM 500GB drive in the new 13" MBP (I even called and spoke to an online chat assistant - seems weird not to have this as an option for the 13"). What is the best/fastest drive 500GB drive that I can get off amazon/newegg/whatever? I don't want an SSD - just not yet maybe in a year or two. I just want a 7200RPM 500GB. Any suggestions? If you have any proof to your claims, or sources I would really appreciate it! Thanks in advance!
