I have a mid 2011 Mac Mini with 1 TB 5400 rpm SSHD (the hybrid hard disk). I am upgrading the memory from 4 gb to 16 gb. At the moment I do not want to invest in a SSD. I would like to know that with 16gb ram and a SSHD (which has its own memory) if I will be able to run El Capitan and Windows 7 in a virtual environment smoothly. Also I would like to know between VMWare and Parallels which is the better virtual environment.
