The first hard drive, created by IBM in 1956, weighed over a ton and had what storage capacity?

5 Megabytes

IBM’s Model 350 stored 5 million six-bit characters—a capacity commonly described as 5 MB—and weighed over a ton with its compressor. In modern eight-bit-byte terms, that data equals about 3.75 MB, making the familiar 5 MB figure a historical shorthand.
