The household's first PC was a P100 with a whopping 8mb of ram, running Win95. Iirc, we purchased it in December 1995, and it came with an 850mb hard drive - which the manufacturer (AST?) had kindly stuffed full of low-resolution tutorial videos.
It's worth bearing in mind that there's been quite a few hardware limits on how big a HDD could be, as detailed here:

When Win95 came out, using more than 540mb (528 after formatting) was still problematic - in 1996, I had huge issues getting a 1GB drive working with a hand-me-down 486, and getting anything over 2GB working was a nightmare for a year or two after that.
