Hey guys, I currently have a 2.0Ghz Macbook with 2Gb of Ram... I have the standard 60Gb hd. I just bought the new Hitachi Travelstar 160Gb with Perpendicular Recording SATA on eBay. I'm just wondering if anyone here bought one? Is the performance good for a 5400rpm drive (better than non-Perpendicular) / Any problems with it? Thanks all!
