How much did the first disk drive weigh?

The first disk drive, known as the IBM 305 RAMAC, was introduced in 1956 and weighed about 10 pounds. This device was revolutionary for its time, allowing data to be stored on magnetic disks rather than relying solely on punched cards or magnetic tapes. The significance lies in its capacity to increase data access speed and efficiency. In the context of early computing, a weight of 10 pounds was considered manageable for a mechanical device that facilitated disk-based storage, setting the stage for the development of subsequent data storage technologies.
