My dad had a 286 with a 40MB hard drive in it. When it spun up it sounded like a plane taking off. A few years later he had a 486 and got a 2gb Seagate hard drive. It was an unimaginable amount of space at the time.
The computer industry in the 90s (and presumably the 80s, I just don't remember it) we're wild. Hardware would be completely obsolete every other year.
My 286er had 2MB RAM and no hard drive, just two 5.25" floppy drives. One to boot the OS from, the other for storage and software.
I upgrade it to 4 MB RAM and bought a 20 MB hard drive, moved EVERY piece of software I had onto it, and it was like 20% full. I sincerely thought that should last forever.
Today I casually send my wife a 10 sec video from the supermarket to choose which yoghurt she wants and that takes up about 25 MB.
We had family computers first, I can't recall original specs but I think my mother added in a 384MB drive to the 486 desktop before buying a win98se prebuilt with a 2GB drive. I remember my uncle calling that Pentium II 350MHZ, 64MB SDRAM, Rage 2 Pro Turbo AGP tower "a NASA computer" haha.
