I will be purchasing a MacBook this summer, and I am thinking of getting the 7200RPM drive over the 5400. I just realized that the 7200RPM option isn't available on the MacBooks! What's the deal with that? Anyway by summer they'll likely change the options. What kind of credence would you give to this article: http://www.mactech.com/articles/mactech/Vol.23/23.01/2301LaptopHardDriveSpeed/index.html Basically it shows that the 7200RPM drives are considerably faster than the 5400's.
