Hard disk drives (HDDs), which use magnetic storage techniques, have been the dominant mass data storage device for computers since the early 1960s and still are for servers today. For data centers the primary advantages of HDDs and key selection criteria are their high capacity, a low cost per bit and long-term data retention.

ST has been a leader in design and manufacturing of analog ASICs and power management solutions for HDDs for over 20 years. ST also offers a wide range of advanced products used in a modern HDD architecture, such as eFuses, temperature and pressure sensors.
