This is what a 20GB hard drive looked like in the early 80's. This is a string of 3380 IBM BE4 drives. It was actually 16 seperate drives. Eash one of these eight units was about the size of a 25 cubic feet refrigerator.
One more thing: Each unit was about $110,000 so the whole string of 20GB would be close to $1,000,000. Now you can buy 50 times that amount of storage, at Costco, for about $100.
My how things have changed and one of the things that amazes me on how computers have evolved.
