The hard drive I had to wipe from the OS, as I mentioned above was a whole 20 gig. 386-ish era. It seemed so huge when I got it (and so expensive) and by the time that PC was done it was... well, a "wipe to OS to fit stuff in" drive.

But that's not necessarily the point, the more relevant thing is how big things are relative to storage and how cheap it is to upgrade storage. It's true that storage sizes and prices plateaued for a while, so a bunch of people are still running on 1-2 TB while the games got into the hundreds of GB. But still, storage had gotten so proportionately cheap before then, and very fast storage is so overkill now. A 1TB Gen 3 NVMe is 75 bucks, and most games will run fine on it, Sony propaganda notwithstanding.
