I am running low on space with my PS4 hard drive but I have a 2TB external USB hard drive that I can connect to the PS4. Is there a way to store games on this drive instead of having them run from the internal hard drive inside the PS4.
While it is likely technically possible, it is not something you should do and it is not something that the PS4 supports. Even with USB 3.0 the read speeds are much slower than they are with a drive that is directly connected to the motherboard using a SATA connection. Reading games from a USB hard drive would be incredibly slow that it wouldn’t be worth the effort of implementing.
