As part of my home backup system I have a USB3 dock that I insert 3TB 'naked' drives for semi-weekly backups that go into my gunsafe (lost the guns in a boating accident) for rotation. Each 3TB has cost me from $200 to a decreasing basis of about $100. My first IBM PC had a 20MB HD Card that cost $800 and was cheap to IBM's HDs.
Our first computer, a 286, cost us $2000. We financed it.
Helped my wife study for college. I used it for video games and programming. :)
Caught flack from the guys at work (at DEC). They were convinced that I was a fool. “Why would anyone want a computer in their home.”
