The hdd is too slow for recent games. Tho older games do work fine on it.
Recent games, mostly AAA ones have a lof of texture streaming with hevy textures. So they wouldn’t be able to load them in time and either generate lag or missing textures.
Older games, even AAA, designed for ps4/xbox one generation don’t seem to need as much drive speed.
For file verification, maybe, tho it wouldn’t bother me much if I didn’t have space on an nvme drive.
