IBM System 305
The IBM System 305, the world's first computer with a hard drive, debuted in 1956 and relied on the random access method of accounting and control (RAMAC) to store data. This is a side view. The entire device required 50 24-inch diameter platters coated with iron oxide paint mounted on a rotating spindle. It held 5MB, or about 1/100th of the amount in flash cards for cameras today.
