Upgrade plans for PS4 and PS5 storage

Getting this down before I forget:

1. I only have a PS4 and no longer have plans for a PS4 Pro because the PS5 is already known to be PS4 backwards-compatible and have faster loading.
2. The standard PS4, like the one I have, doesn't take full advantage of an SSD like a PS4 Pro would.
3. There is no sense in getting the maximum-capacity 2TB SSD, so...
4. I should get a hybrid 2TB hard drive instead.
