Toshiba plans to double HDD production capacity for AI data centers within FY2027 from its 2025 level, targeting a 30% share by storage capacity, up from ~10%
MANILA — Japanese technology group Toshiba plans to double production capacity for hard-disk drives used in artificial intelligence …
Context & Ripple Effects
AI infrastructure demand had already reached storage suppliers in 2025: Seagate and Western Digital shares surged on AI-related HDD demand, while Taiwan-to-US AI server shipments were projected to double that year. Toshiba is turning that supply tightness into a bid to change the HDD capacity-share balance.
The broader storage backdrop also included Kioxia's expectation of roughly 20% annual NAND-demand growth amid the AI boom, showing that data-center buildouts were lifting demand across storage media rather than compute alone.
First-order effects
- Toshiba is committing to double AI-data-center HDD production capacity by FY2027 and is targeting 30% of HDD storage capacity, versus about 10% at the stated 2025 baseline.
- Seagate and Western Digital face a named rival seeking substantially more capacity in the AI-data-center segment that had supported their 2025 market performance.
Second-order effects
- Data-center buyers gain the prospect of a larger third source for AI-oriented HDD capacity, strengthening their procurement leverage if Toshiba delivers the planned expansion.
- The plan puts pressure on Seagate and Western Digital to defend capacity share through their own supply, product, or commercial responses rather than relying solely on constrained supply conditions.
Third-order effects
- If comparable expansions materialize, AI infrastructure spending will reshape the HDD market around storage capacity available to data centers, not simply unit shipments.
- The move extends the AI capex cycle into a broader storage-supply contest, alongside the NAND demand growth already identified by Kioxia.
The trend: AI data-center buildouts are transmitting demand beyond chips and servers into storage capacity, prompting suppliers to pursue share through manufacturing expansion.
