Hard drives were supposed to lose the storage war — but AI demand is now pushing their biggest suppliers years ahead

Artificial intelligence is driving an unexpected resurgence in the demand for conventional hard disk drives (HDDs) as data centers seek cost-effective storage for massive datasets. Toshiba has announced a $380 million investment to expand its manufacturing facilities in the Philippines, aiming to nearly double its production capacity for AI and cloud storage by fiscal 2027. The company plans to introduce higher-capacity drives, with goals to reach 65TB by 2030 and eventually 100TB models. While SSDs offer superior speed, HDDs remain essential for large-scale data retention due to their significantly lower cost. Competitors like Seagate and Western Digital are also reporting strong demand, with production capacity heavily booked through 2028. To maintain competitiveness, Toshiba is automating its production lines to improve yields and reduce staffing needs, while component suppliers are simultaneously scaling up to support the industry's long-term growth in AI infrastructure.
