The world’s data continues to expand—and more of it must be stored and kept accessible indefinitely.
Teams building and operating data centers are under pressure to add capacity without expanding footprint at the same rate. Storage growth now sits at the center of infrastructure planning, especially as AI workloads increase the volume of data that must be retained and retrieved.
Seagate’s Mozaic platform meets this moment with a breakthrough: second-generation HAMR technology that advances recording precision and pushes areal density beyond 4TB per disk.
Enabled by a next-generation suspension architecture and an enhanced system-on-a-chip, Mozaic delivers the processing needed to reliably write and read much smaller bits. The result is a step-change in precision—unlocking higher capacity, efficiency, and value for AI-scale data growth.
With 4+ TB per disk and qualified capacities up to 44TB, Mozaic enables data centers to expand storage within existing space constraints. Built for long-horizon storage at scale under tight physical constraints, Mozaic-based hard drives are bringing heat-assisted magnetic recording (HAMR) into the mainstream at hyperscalers worldwide.
Mozaic has progressed through successive density milestones while scaling manufacturing output. Each step increases data stored per disk and per drive without requiring changes to existing data center architectures.
This latest 4+TB-per-disk milestone extends capacity within the same form factor and supports established deployment models. As density rises, Mozaic-based drives continue to meet rigorous qualification requirements and demanding expansion cycles—helping operators scale with growing data needs.
Mozaic’s 4+TB platform underscores Seagate’s leadership in HAMR-based storage and execution against a roadmap toward 10TB per disk. That execution is now translating into deployment: the latest Mozaic drives — up to 44TB — have cleared qualification in hyperscale production environments and are ramping volume shipments.
For storage teams, the impact is practical. Growth still follows refresh cycles and incremental expansion. Higher Mozaic density means more capacity per rack within existing layouts, using operational patterns already in place across modern data centers.
Delivering density requires precision at every layer. Mozaic hard drives integrate advances in nanophotonics, quantum physics, and materials science—designed, integrated, and tested through atomic-level engineering and exabyte-scale manufacturing.
All Mozaic 4+ hard drives feature Seagate’s custom-designed and manufactured laser technology, reflecting years of investment in nanophotonic engineering for critical HAMR components.
Seagate’s in-house laser production amounts to direct control over key photonics innovation. It translates into improving yield, reliability, and supply-chain resilience. Vertical integration also shortens qualification timelines and supports predictable manufacturing economics.
In modeled one-exabyte deployments, Mozaic improves infrastructure efficiency by approximately 47% compared to standard 30TB drives. This means a reduction of required data center footprint by roughly 100 square feet and lowering annual energy consumption by about 0.8 million kilowatt-hours. At AI scale, incremental density gains translate directly into measurable economic and sustainability advantages.
For data center planners and storage architects, these gains translate into higher capacity per rack, fewer systems required to hit expansion targets, and continued improvements in power and cooling efficiency per unit of stored data.
Mozaic’s scale, efficiency, and qualification agility help customers deliver more exabytes in a capacity-constrained world—future-proofing architectures and supporting returns on AI investments.
Demand for mass-capacity storage continues to rise across cloud, enterprise, and AI-driven environments. Organizations must store, retain, and access more data over longer horizons, even as data centers face constraints on space, power, and time.
As Mozaic advances, these gains support ongoing expansion while preserving core deployments—keeping capacity growth aligned with established planning cycles and infrastructure designs.
Mozaic is Seagate’s leading platform for mass-capacity storage. Its success reflects Seagate’s ability to deliver next-generation capacity at scale, integrate across the stack, and co-plan quickly with customers.
