Every report in this component family is driven by the same structural demand catalyst, confirmed directly by Tom Coughlin (IEEE President 2024, Forbes): nearline HDD shipments grew 13.6% year-over-year in 2025 to approximately 65% of total shipments, projected to exceed 90% of all shipped HDDs by 2030. Because nearline drives require more platters, heads, suspensions, and substrate per drive than consumer drives, this single demand driver propagates through every component market's growth forecast. A recurring structural pattern also repeats across the family: Western Digital and Seagate both operate substantially captive, vertically-integrated component manufacturing, while a small number of independent merchant suppliers serve the residual market, principally Toshiba, the smallest and least vertically-integrated of the three finished-drive makers.
This report profiles Resonac Holdings Corporation, HOYA Corporation, and Seagate Technology and Western Digital Corporation (both captive).
