It was only a matter of time, but Seagate have reached the milestone first by shipping two billion hard disk drives. It took the storage giant 29 years to reach this goal, and more impressively they shipped one billion drives by 2009, and have shipped one billion since.

The one billion drives shipped in the last four years is thanks to the explosion of demand for storage in mobile applications, cloud infrastructures, social media, business applications and the ever increasing consumer market. Steve Luczo, president, CEO and chairman of Seagate, has said: "This is truly an impressive accomplishment and I am proud to lead this company as we celebrate this success."

John Rydning, IDC's research vice president, for hard drives and semiconductors said:

The ever-growing number of mobile and content capture devices using cloud services is fueling the growth of digital content. Mobile devices and the cloud are coming together to drive ongoing demand for hard disk drives, with shipments reaching more than 585 million units in 2013, and hard disk drive Terabyte shipments worldwide growing at a 30 percent 2012-2016 compound annual growth rate.
