Realizing the full value of data

AI has redefined the value of data, and fundamentally changed the economics of storage. Organizations are under increasing pressure to expand storage to meet the relentless growth in data — while optimizing for capacity per square foot, power budgets and new cost structures. More than ever before, success hinges on scale.

Built to scale. Proven to deliver.

Mozaic™ is a breakthrough hard drive platform that harnesses HAMR technology to deliver extreme storage density at scale, accelerating data center capacity expansion and helping customers keep pace with the rapid surge in AI-driven innovation.

4TB+ per disk. Up to 44TB per drive.

With category-defining areal density of 4TB+ per disk, Mozaic unlocks hard drive capacities up to 44TB while preserving a highly efficient 10-disk architecture — allowing data centers to increase storage capacity without expanding physical footprint.

Storage that performs at scale

Mozaic has made HAMR mainstream — delivering the same reliability, performance and quality as today’s mature PMR platforms. Proven in the most demanding hyperscale production environments, it's the standard for AI, cloud and enterprise storage.

Density that drives value

Areal density is the primary driver of hard drive capacity. By dramatically increasing areal density, Mozaic improves data center storage efficiency per square foot and reduces watts per terabyte, while reducing total cost of ownership. 

In large-scale AI, cloud and enterprise environments, the impact is profound. Higher per-disk density allows data center operators to improve real estate ROI for new scale-out or managed fleets — accelerating time to profit while eliminating tradeoffs around what data to keep or delete.

Breakthroughs, refined for reality

Mozaic integrates some of the world’s most advanced nanotechnologies, quantum physics and material science with exabyte‑scale manufacturing — turning breakthrough innovation into rock‑solid reliability and performance at benchmark-setting capacities up to 44TB.

Where engineering meets artistry

Continued reductions in geometries and increased precision across the core Mozaic technologies drive breakthrough gains in areal density, performance and reliability.
