Western Digital has expanded its relationships with the four leading cloud providers over the past year, signing five new supply agreements that secure dedicated capacity for its 20TB and 22TB hard drives. These deals guarantee minimum purchase volumes of 15 million units through 2027, ensuring continuity of revenue streams and reinforcing WDC’s position as a preferred storage partner for AI-driven data centers. Executives have highlighted that these partnerships accelerate joint development on power-optimized designs and firmware enhancements, creating technical barriers that competitors will find difficult to match.

In the most recent quarter, WDC reported a 28% year-over-year increase in shipments of drives with capacities of 16TB and above, totaling over 12 million units. This growth was driven by hyperscaler rollouts of generative AI and machine learning clusters, which demand lower power consumption per terabyte. Shipments to enterprise customers rose by 35%, while overall revenue from data center storage solutions climbed by 22%, contributing to an uplift in average selling prices and reflecting strong end-market demand.

Western Digital has secured early design wins for heat-assisted magnetic recording (HAMR) technology, with plans to ship its first 30TB HAMR drives to select cloud customers later this year. The company has invested over $1.2 billion in its HAMR production line, targeting a transition of at least 50% of quarterly drive volumes to HAMR by mid-2026. These commitments provide WDC with a first-mover advantage in the ultrahigh-capacity segment, where hyperscalers are expected to deploy more than 100 exabytes of storage for AI workloads by 2028.

WDC’s gross margin improved by 180 basis points sequentially, reaching 28.7%, driven by higher-margin enterprise product mix and disciplined cost management. Free cash flow increased by 42% year-over-year to $950 million, enabling the company to return $500 million to shareholders through share repurchases and dividends during the past six months. Management’s target of maintaining at least a 20% free cash flow yield underscores its commitment to capital discipline, offering investors a blend of growth visibility and attractive cash returns.
