I think mine is a MBP 4,1. The hard drive died on me on Thursday so I need to replace it. I have assembled PCs for a while and looking at YouTube videos the process seems straightforward. Will this drive work as a replacement - Western Digital 1TB Scorpio Blue SATA300 8MB 5200RPM Mobile Hard Drive I mostly use this laptop for Office, net related stuff and some light gaming. Will I be regretting the 5200rpm sometime down the line?
