Western Digital (WD) has sold its entire hard disk drive (HDD) production capacity for 2026, according to a statement made by CEO Irving Tan during the company’s Q2 2026 earnings call on February 17, 2026. The announcement signals a potential supply crunch in the storage market, driven by escalating demand from the artificial intelligence sector.
“As we highlighted, we’re pretty much sold out for calendar 2026,” Tan stated, as reported by multiple sources including Tom’s Hardware and TheGamer. “We have firm [purchase orders] with our top seven customers.” WD has also secured long-term agreements (LTAs) with two customers for 2027 and one for 2028, encompassing both storage volume measured in exabytes and pre-negotiated pricing.
The surge in HDD demand is directly linked to the rapid expansion of cloud infrastructure and large-scale data centers required to support the development and deployment of AI technologies, according to a report from PCPAI. While solid-state drives (SSDs) offer superior speed, HDDs remain a cost-effective solution for storing the massive datasets needed for AI training, inference logging, system backups, and web scraping – often referred to as “cold” and “warm” data.
Western Digital’s financial reports indicate a significant shift in revenue streams, with 89% now originating from its cloud and enterprise businesses, while the consumer market accounts for only 5%. This shift reflects a strategic prioritization of serving hyperscalers and cloud service providers, who are aggressively building out AI infrastructure. The cost efficiency of HDDs, now trading at more than 16x the price of an equivalent HDD, is a key factor in this dynamic, according to Tom’s Hardware.
The HDD market is currently dominated by three major players: Seagate Technology, Western Digital, and Toshiba. With WD’s 2026 capacity fully committed, industry analysts anticipate potential price increases and extended lead times for HDD purchases. The situation echoes recent shortages experienced in the DRAM and NAND flash memory markets, both critical components for AI systems.
The long-term agreements established by Western Digital suggest that its customers do not anticipate a near-term resolution to the memory and storage shortages. The company’s VP for Investor Relations, Ambrish Srivastava, indicated that the focus on enterprise clients mirrors a trend among memory chip manufacturers prioritizing the more lucrative HBMs demanded by hyperscalers.
