Hi all, quick question here. I have a MBP and I plan to upgrade the 200GB 5400 RPM stock HDD for WD's 320GB 7200 RPM. I went to system profiler and found out that it actually says that Intel SATA controller runs at 1.5 GB/s so I was confused because if I'm going to buy an HDD that runs at 3 GB/s but if my computer does not even support that speed, then what's the point right? But I did some more research and found out that the stock MBP (previous gen 4,1. 2.4 GHz) HDD is Fujitsu MHY2200BH which runs at 1.5 GB/s. So my question is If I upgrade to the 3 GB/s HDD will the Intel SATA controller support it and run at 3 GB/s? I mean is system profiler only stating that Intel SATA controller runs at that speed because it is the speed it's running at right now, or is it showing a fixed speed that the controller has regardless of the HDD speed (1.5/3GB/s)? System Profiler Info: Intel ICH8-M AHCI: Vendor: Intel Product: ICH8-M AHCI Speed: 1.5 Gigabit Description: AHCI Version 1.10 Supported FUJITSU MHY2200BH: Capacity: 186.31 GB Model: FUJITSU MHY2200BH Revision: 0081000D Serial Number: K43BT882HBTG Native Command Queuing: Yes Queue Depth: 32 Removable Media: No Detachable Drive: No BSD Name: disk0 Mac OS 9 Drivers: No Partition Map Type: GPT (GUID Partition Table) S.M.A.R.T. status: Verified Thanks! Hope I was at least a bit clear.
