AI-driven data accumulation (autonomous driving, robots, etc.) requires massive, low-cost archival storage. HDDs are far cheaper per unit and higher capacity than SSDs, making them essential for cold and long-term data. The HDD industry is an effective oligopoly (Western Digital, Seagate, Toshiba private) and is not expanding capacity because firms fear eventual SSD technological displacement; this cautious capex limits supply. Meanwhile, big tech companies have already locked in long-term supply contracts through 2032, ensuring demand visibility. With no supply response and secular demand growth, the supply-demand imbalance is bullish for HDD stocks, and major banks (Morgan Stanley, J.P. Morgan) are raising price targets. This asymmetric setup is still in early innings.
