I have MBP15" Mid 2009 model Core 2 Duo 2.66Ghz RAM 4GB 9600+9400 Now I am using the WD Scorpio Black 7200RPM 320GB. I will go to Canada next month, So I am considering to buy a SSD. What brand should I go for? I have the Corsair Force 120GB and OCZ Vertex 2 120GB in my mind. or I should still use HDD instead? another question They said that this nvidia chipset model have a problem when there HDD are replaced is that true? I've change from the original Hitachi 320GB to the WD drive ,but it still working flawlessly..
