I am looking to improve on performance a bit by adding an SSD. I know the performance will be better if everything was on it, but would installing it as a cache an using the WD Black 1 TB drive as normal get better performance over a wider array of programs? I'm looking to get either a 120GB SSD for cache or 180/240GB SSD to use as boot.
Any advice? Also, suggestions about learning to create an SSD as a cache.
