How does Mozaic reach 4TB per disk and 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.
Learn more about areal density
How does Mozaic areal density lower watts per terabyte?
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.
Is HAMR proven in hyperscale production environments?
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.
See how we do itHow does Seagate manufacture Mozaic at exabyte scale?
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.
Which core technologies make up the Mozaic platform?
Continued reductions in geometries and increased precision across the core Mozaic technologies drive breakthrough gains in areal density, performance and reliability.
Gen 2 superlattice platinum-alloy media
Mozaic's Gen 2 superlattice platinum-alloy media dramatically increases magnetic grain stability at reduced sizes — enabling 4TB+ per disk while maintaining the thermal stability required for long-term data retention.
Gen 2 plasmonic writer
The plasmonic writer focuses a near-field light spot smaller than the diffraction limit directly onto the recording medium, enabling the precise, localized heating that makes HAMR recording possible at extreme areal densities.
Gen 8 spintronic reader
The Gen 8 spintronic reader achieves the signal sensitivity required to reliably read data from the smaller, more densely packed magnetic grains that Mozaic's increased areal density demands.
7nm integrated controller
Fabricated at 7nm, Mozaic's integrated controller delivers the processing power needed to manage real-time signal processing, error correction and channel management at the data rates and densities that define the platform.
What is the Mozaic roadmap to 100TB?
With a clear roadmap to 100TB and beyond, Mozaic delivers the continuity data centers need to plan, deploy and scale with confidence for the next decade. Each new platform generation builds on frontier innovation, proven engineering and manufacturing scale to unlock the capacities for tomorrow's data demands.
Which Exos systems deploy Mozaic drives?

Seagate Mozaic platform: frequently asked questions
Everything you need to know about the Seagate Mozaic Platform and how BlueAlly can help you deploy it.
The Seagate Mozaic™ Platform is a breakthrough hard drive platform that harnesses Heat-Assisted Magnetic Recording (HAMR) technology to deliver extreme storage density at scale. It achieves a category-defining areal density of 4TB+ per disk and supports hard drive capacities up to 44TB — all within a highly efficient 10-disk architecture.
HAMR — Heat-Assisted Magnetic Recording — uses a near-field laser integrated into the recording head to temporarily heat a tiny spot on the magnetic disk. This reduces the coercivity of the medium at the write point, allowing data to be written to smaller, more stable magnetic grains. Once cooled, the grains retain the recorded data with exceptional long-term stability.
Mozaic delivers the same proven reliability, performance and quality as today's mature PMR platforms — while unlocking significantly higher areal density. Proven in demanding hyperscale production environments, Mozaic has made HAMR mainstream as the standard for AI, cloud and enterprise storage.
Seagate's roadmap targets 100TB and beyond. Current Mozaic drives deliver up to 44TB. The roadmap extends through 2033, with each platform generation building on proven engineering, frontier innovation and manufacturing scale to meet growing AI and cloud infrastructure demands.
Higher areal density means more data per disk and per drive, which directly reduces the watts per terabyte consumed and the physical data center real estate required per petabyte of storage. In large-scale AI, cloud and enterprise environments, Seagate reports that in a one-exabyte deployment Mozaic improves infrastructure efficiency by approximately 47% compared to standard 30TB deployments, which translates to measurable reductions in CapEx, OpEx and carbon footprint.
