This document provides a timeline of important developments in hard disk drive technology from 1956 to 2009. Some of the key events include the introduction of the first disk drive by IBM in 1956. By the 1980s, hard disk drives had become standard on all but the cheapest PCs due to reduced costs. In 1999, IBM released micro hard drives with capacities of 170MB and 340MB. The first 2.0 terabyte hard drive was released in 2009.
