Hi guys, I'm still eagerly waiting for my new Macbook to arrive (probably on Monday by the looks of things). I did get myself a Seagate Momentus 7200.3 16MB Cache 7200RPM drive to prepare for it. So in the mean time I decided to use HDTune to check the difference between a Seagate 5400.3 Hard drive. It looks like it is worth the upgrade I'll post real life testing later (e.g. boot time) when I get my Macbook.
