IBM’s 5MB Hard Drive, 1956: When Data Meant Heavy Lifting
In 1956, IBM unveiled a milestone in computing history: one of the world’s first commercial hard drives, capable of storing a then-staggering 5 megabytes of data. The machine was massive—over a ton in weight and roughly the size of two refrigerators—containing 50 spinning magnetic platters and offering a data access time of 600 milliseconds.
This leap forward came at a steep cost: $3,200 per month in rental fees, equivalent to more than $38,000 today. Yet for businesses moving beyond punch cards and magnetic tape, the investment promised unprecedented speed and flexibility.
Today, 5MB is hardly enough for a handful of photos—let alone a modern file—but in its time, IBM’s hard drive represented the cutting edge. It remains a towering reminder of how far digital storage has come, from bulky metal giants to invisible clouds.
