I have a late 2008 Santa Rosa 17" MacBook Pro 3,1 that I'd like to upgrade. Goal: 240GB SSD Current Specs: OS X 10.8.4 2.6GHz Core 2 Duo Hitachi 200GB, 1.5 Gigabit, 7200-rpm I am aware that 6Gbps is a waste of money since my model can only achieve 1.5Gbps. So I'm looking at 3Gbps SSD. I am looking at the OWC Mercury Electra 3G SSD. Smart? Stupid? Alternatives? Thanks.
