I have an early 2011 MBP I looked here: http://en.wikipedia.org/wiki/MacBook_Pro says I should get 6GBs on my hard drive. I got a new ADATA SP900 and the speeds are horrid! I have attached the picture below ... I should be getting somewhere around ... Read : Up to 550MB/s Write : Up to 505MB/s I am not even getting half that ... I am getting 3Gbps speeds is the wiki link wrong on their info?
