IBM invented the first hard disk drive (HDD) in 1956 as part of the RAMAC (Random Access Method of Accounting and Control) system. The RAMAC 350 stored 5 MB of data on 50 24-inch platters and was the size of two refrigerators. IBM's innovation made random access to large amounts of data possible, revolutionizing data storage. Apple, Microsoft, and Western Digital entered the storage market much later.
