Hi, I have a MB mid-2010 version 7,1 with its original base level, factory components still installed. 2 GB RAM, 250 GB SATA ect. I'm going to bump it up to 8GB of RAM and install the Seagate Momentus XT Hybrid 500GB as my main drive. Should I consider installing a second drive in the OptiBay? How do I do that? Will it increase performance significantly if done right? Let me know your thoughts.
