I wanted to know if anyone has put a SSD in their macbook optical bay and used the SSD to run their operating system? The reason is I could use the original drive bay location for with the original drive (wiped clean for file storage) or future large one with easy access without having to rip the laptop apart in the future. Also can you change the booting of the macbook without too much trouble from the original drive to where the optical drive would have been? My optical drive is damaged and rather than replace it with another I wanted to explore my options and the Solid State Drive looked interesting. The second question is how small of a SSD will the Macbook need to run? There is no sense paying for a big SSD just for running the OSX (or is there)? Any comments are welcomed.
