About This Statistic
This statistic shows global shipment figures for hard disk drives since the fourth quarter of 2010. In the third quarter of 2016, approximately 144.6 million hard disk drives were shipped worldwide. A hard disk drive (HDD) is a data storage device which is used for storing and retrieving digital information. It is a form of non-volatile memory, meaning that it retains its data even when unpowered. The technology was first introduced by IBM in 1956 and it has been the dominant secondary storage device for general-purpose computers since the 1960s. The main competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs). HDDs are expected to remain the most used secondary storage because of a greater recording capacity, a better price per unit of storage, and a longer product lifetime. The advantages offered by SSDs over HDDs is that they are faster, generally more durable, and consume less power.
