When I first bought my macbook pro (2010 13") over a year ago the hard drive failed within two weeks. I didn't feel like sending it back to apple and there's no stores close to me so I just replaced it with a hitachi travelstar 5400rpm HDD. Two months later - FAIL. I replace it again with a WD 500GB HDD - this time it lasts about 5 months, then it fails. So I just can't deal with it anymore, I'm done with mechanical drives in my laptops. it's not like I'm not careful with it, I always put it to sleep and wait until the sleep indicator light comes on before I move it. So I stuck in a OCZ 240GB solid state drive - it's great. Never going back to traditional HDD's again, it's amazing computers are still being made with them.
