Hello everyone, I'm looking to upgrade my mid 2012 macbook pro model, currently its a 2.5 GHz i5 with 4GB 1600 DDR3 RAM and 500 GB HDD. I'm looking to upgrade both the RAM and the Hard Drive. For the RAM; I'm looking at Corsair vengeance and G.Skill ripjaws, but I'm wondering if I should go with CL9 or CL11 and whether I should get a 1.35V or 1.5V. I've looked up on many forums, i haven't found any conclusive opinion on whether my Macbook pro requires a 1.5 Volt RAM or 1.35V. And also if my macbook supports CL 11 or CL 9. The lower the Cas Latency the better, but many have suggested that i stick with CL 11 because it has to match the timing of my motherboard. Can you suggest the most suited RAM for my Mid 2012 Macbook pro. For the hard drive; I'm torn between a SSD (http://www.newegg.com/Product/Product.aspx?Item=N82E16820147248) and the Hybrid SDD by Seagate (http://www.newegg.ca/Product/Product.aspx?Item=N82E16822178340) I'm wondering how good the Hybrid drives really are? Are they really on par with the SSD, with regards to performance and speed? And how reliable is it? I've read some reviews about it crashing within few months of installation, are there any concerns with its reliability?
