$STX vs $WDC: Weighing Two Key Players in the AI Storage Cycle Both STX and WDC are riding an AI-driven surge in demand for high-capacity hard disk drives (HDDs), making them two of the strongest large-cap performers in the broader technology sector. WDC repositioned itself as a pure-play HDD leader after spinning off its flash memory business, SanDisk, while STX retains a more diversified storage footprint. STX holds an early technology lead in HAMR (Heat-Assisted Magnetic Recording), whereas WDC has leaned on ePMR and UltraSMR drives for current-generation capacity gains. Both companies have locked in multi-year, build-to-order agreements with major cloud customers, improving revenue visibility into calendar 2026 and beyond.
