Today's $60 1TB drive would have cost $1 trillion in the 1950s

A brief history of the hard drive

Excerpt:

In the 1950s, storage hardware was measured in feet—and in tons. Back then, the era's state-of-the-art computer drive was found in IBM's RAMAC 305; it consisted of two refrigerator-size boxes that weighed about a ton each. One box held 40 24-inch dual-sided magnetic disk platters; a carriage with two recording heads suspended by compressed air moved up and down the stack to access the disks. The other cabinet contained the data processing unit, the magnetic process drum, magnetic core register and electronic logical and arithmetic circuits.
