Nidec slashed its forward guidance for 2019 HDD shipment forecast from 356 million drives to 309 million drives. Expects shipments in 2020 to sink even further, down to 290 million units.An HDD is a non-volatile memory hardware device that stores and retrieves data on a computer. The presentation noted the emergence of solid-state drives (SDD) in desktops and laptops, will lead to further declines in shipments well into the early 2020s. That is not just due to the global slowdown in electronics, but SSD has tremendous benefits over HDD including no moving parts and flash memory to store data.

The decline in the PC market has been one of the most significant decreases YoY ever, with 289 million units shipped in 2013 and only 65 million expected in 2019. The presentation's figures show a further decline in 2020, down to just 46 million.

Hard drive sales have been on the decline since 2013, and while HDD will still have adequate demand from data centers, Nidec is already looking elsewhere for potential new revenue streams. As hard drive sales and revenue wane, the Japanese motor manufacturer is expected to complete a restructuring to address new growth areas (repurposing its facilities to address key growth areas like automotive, robotics, and 5G), by the early 2020s.
