SSDs still degrade, though - Optane was mooted for something like this, but still ended up being too expensive and not good enough at either (unprofitable) in the end.

Pushing 10GB/s on an SSD with 1000TBW write endurance would kill it in ~ 100000s, or a little over a day of continuous usage - and I'd expect a GPU probably would come kind of close.
