Western Digital used its Innovation Day 2026 to signal a decisive shift in how it sees its role in the AI-driven data economy, unveiling a customer-centric storage roadmap designed to reinvent the hard drive for artificial intelligence workloads. The company said the strategy reflects a deep transformation of its business, enabling new storage technologies that balance scalable capacity, performance, power efficiency and cost economics at a time when AI is generating unprecedented volumes of data.

Demand for storage has intensified as AI training and inference workloads expand, placing pressure on infrastructure to deliver reliable capacity, predictable performance and faster qualification cycles without disrupting operations. Western Digital said its latest technologies directly address these needs, with a particular focus on hyperscale and enterprise customers seeking to scale efficiently.

The announcements build on strategic changes completed over the past year, including a move to long-term, multi-year customer partnerships, disciplined execution that more than doubled gross profit year-over-year, and leadership renewal aimed at accelerating decision-making. These moves helped drive the company’s inclusion in the Nasdaq 100 and its ranking among the top S&P 500 performers in 2025. A refreshed financial model outlining the next three to five years was also shared with investors.

As part of this momentum, the company formally introduced updated branding under the simplified name WD, visually aligned with data centre infrastructure and its positioning as a foundational storage partner for AI.

A central theme of the roadmap is capacity innovation. WD confirmed that its 40TB UltraSMR ePMR hard drive, currently the world’s highest-capacity model, is in qualification with two hyperscale customers, with volume production planned for the second half of 2026. HAMR-based drives are also in qualification, with ramp production targeted for 2027. The company said it will extend ePMR technology to 60TB while scaling HAMR to 100TB by 2029, offering customers flexibility without forced technology transitions.

Performance was another focal point, with WD introducing High Bandwidth Drive Technology and Dual Pivot Technology to close the gap between HDDs and QLC flash for AI workloads. Combined, the innovations are expected to deliver up to four times the sequential IO while preserving cost and capacity advantages.

Power efficiency also featured prominently, with power-optimised HDDs aimed at AI data that is cold but still needs rapid access. These drives are expected to enter customer qualification in 2027. Alongside this, WD announced an expansion of its Platforms business, including an intelligent software layer with an open API planned for 2027 to help mid-scale customers achieve hyperscale-level storage economics.

“For the past year, WD has remained continuously focused on execution and accelerating innovation, which has enabled us to truly reimagine the hard drive to meet the requirements of AI,” said Irving Tan, Chief Executive Officer at WD. “Today, we are showcasing innovation that reflects our deep connection to our customers and how we are meeting demand for capacity, scale, quality, enhanced performance, and ease of technology adoption.”

“WD Innovation Day is where our customer-centric business transformation meets our breakthrough technology for the AI era,” said Ahmed Shihab, Chief Product Officer at WD. “We've organized around how customers build and scale AI infrastructure. WD is challenging conventional storage assumptions and removing the complexity and cost barriers that limit their AI-driven growth. Our capacity, performance, power efficiency, and platform innovations solidify our position as the innovation partner for the AI-driven data economy.”

Industry analysts also pointed to early market validation. “WD's Innovation Day revealed a company that has genuinely transformed its strategy around customer infrastructure needs,” said Ed Burns, HDD Research Director at IDC. “The market validation is already evident – customers are deploying these solutions because WD is solving what matters most for AI infrastructure: reliable capacity at scale, performance that meets demanding workloads, and economics that enable profitability. This customer-centric approach, combined with operational discipline positions WD well in the market going forward.”
