The world's first hard drive was introduced in September 1956 by IBM, called the IBM 350, it was part of the IBM RAMAC 305, the first computer to use a hard drive.

In case you're wondering what RAMAC stood for we won't disappoint you; 'Random Access Method of Accounting and Control.'

Now bear in mind that computer stuff was really big back in 1956 and the IBM 350 was no different, it contained fifty 24 inch two-sided discs on which data was stored, housed in a cabinet 5 feet long, 5 feet 8 inches high and 2 feet 5 inches deep.

It weighed a ton, no really, it weighed one ton.

Now if you're thinking this thing had amazing storage capacity we won't disappoint you, it could hold 35,000,000 bits, which is 4,375,000 bytes or a whopping 4.17 megabytes.

Those lucky enough to get their hands on the IBM 350 had to shell out $3,200.00 USD, and that's just for 1 month of the lease.
