This is a picture of an IBM hard drive being loaded onto an airplane in 1956. According to @HistoricalPics, which tweeted the picture, it’s a 5 mega-byte drive, and it weighed more than 2,000 pounds.
To put that in context, 55 years later, the weakest iPhone 5S has a 16 gigabyte drive, about 3,200-times as big. And it weighs a quarter of a pound. The IBM hard drive could have stored exactly one iPhone picture, and nothing more.
