Quick and dirty question to the wise ones around: I normally use 200 GB of my storage drive plus OS. Therefore I'm thinking I should not upgrade the ssd to 1 TB and instead go with the processor bump from 2.5 to 2.8. However some people said even though I won't be using even half of the 500 GB, getting the 1 TB would still bring performance improvements to the macbook. How true is that? Is there really a difference in speed between 500 GB and 1TB? And in my case, due to low storage use, wouldnt the proc bump make it snappier overall?
