So I bought my Macbook in Spring of 09' I believe and it came with a 160 GB hard drive that has only about 8 GB of space left. I am looking to upgrade but have a few questions... 1) What are the top hard drives recommended that has above 300 GB of space? In terms of speed, quiet, battery life, quality, etc. 2) How would I make this replacement without losing what I have on this old hard drive...I'd like to transfer my stuff on this Hard drive onto the new one. 3) I would have to install Lion onto the new hard drive from my CD correct?
