Have bought the drive because my new MB retina has no drive installed - and am fully satisfied. Since you have anyway less optical storage media (at least is that with me so), the connecting and disconnecting the drive does not really bother the workflow. For the few times when I import a CD into my iTunes Bib, something burning or reliable data for the company, the drive is really good. Also the DVD Check the drive is fast, almost silently, very very low vibration and very energy efficient (as far as I can tell). Only marginal negative points are the many times long wait until a CD reissued.
