WD Advances Next-Generation Trusted Infrastructure with Industry’s First Post-Quantum Cryptography Hard Drives to Help Secure the Future of AI Data

About this update from Western Digital Corporation

Ultrastar® HDDs currently in customer qualification introduce PQC-ready secure boot and firmware protection, establishing a new standard for device trust in the Quantum Era SAN JOSE, Calif., May 18, 2026--(BUSINESS WIRE)--Western Digital Corporation (Nasdaq: WDC), the storage foundation of the AI-driven data economy, today announced a significant step in next-generation infrastructure security with the integration of post-quantum cryptography (PQC) into its newest high-capacity Ultrastar® UltraSMR hard disk drives. As AI infrastructure evolves from compute-centric deployments to data systems that persistently retain information across every inference, training run, and interaction, the durability and security of that data becomes foundational, not optional. These drives are currently in qualification with multiple hyperscale customers, reflecting strong early interest in quantum-resilient storage architectures. AI data systems generate and retain massive, long-lived data sets. Securing that data over decades, not just years, must be a core requirement of modern infrastructure. WD's launch of the first hard drives to implement NIST-approved quantum-resistant algorithms marks a definitive industry transition — from theoretical planning to deployed hardware-level defense. By hardening the root of trust, WD provides a critical safeguard against threats like harvest now, decrypt later (HNDL) and similar attacks. This helps protect the massive data lakes fueling today’s AI innovations against the cryptographic protection-breaking power of tomorrow’s quantum computers. WD is among the first to bring post-quantum cryptography into production storage infrastructure, helping lead the industry’s quantum transition with deployed, standards-aligned, infrastructure-level protection, setting a new baseline for trust in AI-era data systems. Why Post-Quantum Storage Security Matters Now As AI infrastructure and workloads generate and retain data in perpetuity, the value of that accumulated data grows, and so does the urgency to protect it against threats that are advancing faster than most organizations anticipate. WD's PQC Implementation WD's PQC implementation on the new Ultrastar DC HC6100 UltraSMR is designed to help protect device trust chains from manufacturing through field service. This implementation represents more than a feature enhancement; it refl...
