I bought my MBP on ebay. It's a 2.4 Ghz Core 2 Duo with the high-res screen. It was advertised as having a 5400 RPM 160 GB Hard drive, and I was thinking of upgrading it to a 7200 RPM drive. However, I went into system profiler and found this. Intel ICH8-M AHCI: Vendor: Intel Product: ICH8-M AHCI Speed: 1.5 Gigabit Description: AHCI Version 1.10 Supported ST9160823AS: Capacity: 149.05 GB Model: ST9160823AS Revision: 3.DAE Serial Number: 5NK07N1S I googled that model #, and it comes up with the Seagate Momentus 7200.2, which is a 7200 RPM drive. Can anyone confirm this? Did I just get really lucky? Thanks!
