Will I notice a diference in booting speeds?

(actually, real question would be: Is it faster than the original sata, and if so, how much faster and how will it affect me?

Is a 8gb early 2011 macbook pro maxed out, or can I upgrade to 16?

I'm asking because I read in http://www.crucial.com/store/mpartspecs.... that it can actually take 16gb. Thanks!
