I'm thinking about getting some last gen ones at some stage once the prices are right switch out the 1tb's for 2-4tb ones, have one running at 3000+ and the other at 1800ish games load fast enough off them, it more comes down to direct storage benifits.
This only makes sense if you're building a Star Wars themed PC. In any other scenario it would stick out like a sore thumb. But there's a market for everything.
