Hi, I'm a college student with a macbook pro 13 inch, early 2011 model. All I use it for is microsoft word, itunes, and google chrome. (I know a MBP is overkill for these tasks). I noticed my hard drive is running a bit slow, takes a while to go past the spinning disco ball thing when loading a simple app such as a pdf book. Would installing a ssd and taking out the original 320 gb hard drive be overkill for what I use the macbook pro for? Thanks.
