When I first got my Macbook Pro I cloned a 250Gb in the result of a major crash. Since then it has been sitting in a 2.5 enclosure in my drawer. I never imagined that I would use as my primary drive, it was just an afterthought. I wanted to switch to a larger drive and I was going to clone it to save time. Has anyone run into issues with a clone as their primary drive? In short is a cloned drive going perform the same as a fresh install?
