It was a Pentium 100Mhz, 16MB RAM, 1MB dedicated video card and a 1GB hard drive.
My first "affordable" upgrade after my 386 40Mhz was the Pentium 90 Mhz and a 128 MB disk, a just under the top of the line PC for fl 2000,-.
I was never a data hoarder and didn't need expensive large disks, and nowadays I use 2x 500 GB in Btrfs RAID 1 on my laptops with an about 300 GB volume for miscellaneous data (mostly occupied by game and media downloads). It's just about the right size that when it's close to filling up I feel that I have too much junk on it and need to clean it up.
The two data servers I use have barely more than 1 TB (also Btrfs RAID 1) each, on which I store my ripped CDs and DVDs, each about 90% used, so 100 TB would leave 98 TB of wasted space. Even if I had that I can only imagine it being usable by splitting it into 1 TB volumes to keep maintenance and rebuild times in check.
500 GB SSDs are now at pricepoint that I choose to buy them over spinning rust and don't worry about a failed drive. I recently bought a replacement for a Verbatim 500 GB that failed after a year and a half because it's not worth the hassle to claim warranty.
