IBM announced the world’s first HDD, the 3.75MB RAMAC 350 disk storage unit, 69 years ago today — unit weighed more than a ton, 50 platters ran at 1,200 RPM
This massive stacked magnetic disk design earned the nickname the ‘baloney slicer.’

The RAMAC is almost 70 years old. It was the first hard-disk system for the first computersystems in America. It allowed the retrieval and manipulation of data in seconds, instead of hours and days with magnetic tape drives.
Our modern world is the way it is also because of that invention.
