Seagate has introduced its Mozaic 4+ platform, leveraging heat-assisted magnetic recording (HAMR) technology. The company outlined a long-term roadmap aiming to reach 100TB hard drive capacities by 2032 to address increasing data center storage demands.
Context
In March 2026, Seagate announced the launch of its Mozaic 4+ platform, a major leap in hard drive density that utilizes second-generation Heat-Assisted Magnetic Recording (HAMR) technology. This platform enables capacities of up to 44TB per drive by achieving an areal density of 4TB+ per platter. The company confirmed that these high-capacity drives have already begun volume shipments to two leading hyperscale cloud providers, signaling that the technology has successfully moved from lab testing into production-scale AI infrastructure.
This development is critical for the semiconductor and storage supply chains as AI workloads drive an insatiable demand for mass data retention. Seagate claims the Mozaic 4+ improves data center infrastructure efficiency by roughly 47% compared to standard 30TB drives, offering significant savings in floor space and power consumption. Looking ahead, Seagate has established a long-term roadmap that aims to reach 10TB per platter, targeting a 100TB hard drive capacity by 2032 to support the next era of multimodal AI training.
