I am buying 13" Macbook Pro next week and I was wondering which hard drive I should go for? I will be buying the hard drive and upgrading it myself, but which of these would be better? The 320GB Western Digital Black 7200rpm Hard Drive with no Free Fall or The 500GB Western Digital Blue 5400rpm Hard Drive with no Free Fall I have heard that the WD Blue drives are equal to other 7200rpm drives but is that really true? I've always had a 5400rpm hard drive in laptops so it would be nice to have something faster for a change. I would say 320GB would be sufficient capacity wise, but more would be better (although not at the sacrifice of speed).
