If you think your desktop computer takes up too much space, consider yourself lucky that you weren’t in the computer business back in 1956. A 5-megabyte hard drive required a forklift just to move it around back then, as seen in this photo from The Next Web [2] of an IBM 305 RAMAC.
Dubbed a ‘supercomputer’ back in the day, the 5MB hard drive weighed more than a ton. Compare that with a 1.5-terabyte external drive that weighs less than 3 pounds today. We’ve come a long way, baby.
