I have a mid-2012 15” non-Retina Mac book pro with a 1TB hard drive. I decided that I wanted to make my system faster by replacing the hard drive with an ssd and while I was at it I decided I also wanted to have Windows and Ubuntu partitions. Doing it this way meant that I had no data on the SSD while I experimented with partitions and boot managers although everything I did should be possible on a drive with an existing system.
