Hi guys, I am just in the midst of my research of whether the new MBP 17" is accepting the new SAS drive with 15,000 RPM? What's the fastest can it fit other than SSD? Because SSD are just too expensive. I was looking for something like the Seagate Cheetah. And also another question with the 8GB DDR3, does anyone know where I can get the cheapest and most reliable product from? Please give me some advice. Thanks in advance!
