I think you meant HDD speed, not HDD storage. Blockchain size is only 250GB which is small compared to today's customer HDD capacity (0.5 - 8TB)
No, I was indeed talking about the HDD storage but you are right that today 250GB is not so much and 1TB is slowly a standard or a bare minimum for every more advanced computer user.
Actually, my biggest HDD is 250GB and I don't think I will fill it completely at any time soon.
Everything is changing because a few years I've always had too little memory and had to buy extra or larger ones if they were available.
Filling any memory for me wasn't a problem because I was storing a lot of video files, but nowadays with video streaming and all these movie services just don't have such a need.
