Western Digital, the storage foundation of the AI-driven data economy, has 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 defence. 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.

“As AI data compounds and becomes more valuable and long-lived, securing it for the future is no longer optional. Quantum computing represents one of the most significant technology transitions of our time and it is advancing faster than many organisations anticipate. The security architectures that have protected enterprise storage for more than a decade will need to evolve,” said Dr Xiaodong (Carl) Che, CTO and Senior VP, WD. “Integrating post-quantum cryptography into our Ultrastar enterprise-class drives is part of our commitment to helping customers stay ahead of threats that are already present in the form of HNDL attacks. By aligning with NIST standards and CNSA 2.0 today, we are helping enterprises build a clear, low-friction path to quantum-safe storage infrastructure.”
