Hi, I'm a mac user for 6 years now but new on MacRumors forum. I'm also not a native English speaker, so excuse some of my language mistakes. Here's the situation. I plan to replace my SuperDrive with my actual HDD and want to put a Sata III ssd in the HDD compartment. Why a Sata III while my MBP only support Sata II ? Because : - when I'll sell my actual laptop I want to keep this hardware and eventually install it on my new laptop that will be full Sata III since then. - in my country Sata II SSD are hard to find and if so, they cost the same price that Sata III ! Is it possible to get a Sata III SSD for my MBP (mid 2009) ? Has anyone done that ? How does it work ? For those who have installed a Sata II SSD (on HDD compartment) on a 2009 MBP (or earlier), did you encounter any problem ? Which one(s) ? As you see I'm a bit worry : I though installing an SSD drive would be "easy" but I read a lot of posts reporting issues with these disks. Thanks for your advices.
