All the engineers where I was working got dual-floppy IBM PCs---managers got an XT (mainly for the same reason they had offices to themselves and speakerphones and us engineering grunts didn't). My co-workers thought I was nuts for getting an XT-clone (Columbia) with the whopping 10MB Tandon HD. That was soon outgrown as was its 20MB replacement. My next computer had a 40MB HD---more storage than DOS could even handle w/o help. I soon got tired of buying replacement disks so when my 486 arrived, I tossed in a pair of 200MB SCSI disks. Now we don't think twice about running to the store for TB drives. For comparison, up until ~10 years ago, I managed a cluster at an F500 company's running their sales database applications that only had access to about 1.5TB. We've become the Everett Dirksons of home computing: A TB here, a TB there, and pretty soon you're talking about real disk space.
