I am currently debating about whether or not to upgrade the HD, and Ram in my Early 2011 MBP or save up and purchase a new MBP down the road. My MBP currently is a 2.3GHz, with 4GB of Ram, and 320GB Hard Drive. I'm considering putting in a 850 Evo SSD, and upgrading the ram to 8GB. My concern is that when I go into the System Information the current HD it says Link Speed is 6GB but it says Negotiated Link Speed is only 3GB so I don't want to put new hardware into it if the machine will not be able to handle it. Any advice or feedback would be greatly appreciated.
