I finally got around to upgrading my 2014 Mac mini with a solid state drive (SSD). The difference is like night and day. If you’re using one of these models and you’re looking for a good way to bump up the performance, an SSD is, quite frankly, one of the only things you can do (unlike older Mac minis, Apple soldered the RAM in place). Regardless, I strongly recommend considering it – not just for a 2014 Mac mini, but for any older Mac you’d like to pep up.
