Seagate launches Mozaic 4+ HAMR hard drives up to 44 TB

Seagate Technology has introduced its next-generation Mozaic 4+ platform, described as the industry’s only heat-assisted magnetic recording (HAMR) based storage platform deployed at-scale, targeting rapidly growing requirements for scalable, efficient and high-performance storage. The platform is now qualified and in production with two leading hyperscale cloud providers, reflecting production-scale deployments in hyperscale environments that demand very high capacity and reliability.

The Mozaic 4+ platform currently supports capacities up to 44 TB, positioning it as a high-density option for cloud and enterprise workloads that generate and process increasing volumes of data. Seagate states that it is executing on a roadmap to scale from today’s 4+TB per-disk toward a future 10 TB per-disk, which is intended to enable hard drive capacities of up to 100 TB for data center and cloud customers seeking long-term capacity growth without major infrastructure changes.

To achieve these density gains, the platform incorporates a next-generation suspension architecture and an enhanced system-on-a-chip designed to enable precise recording at higher areal densities while maintaining enterprise-class reliability. According to Seagate, each generation of the Mozaic 4+ platform is structured to deliver continued capacity increases without requiring disruptive architectural shifts, allowing customers to adopt larger drives within existing systems and operational models as additional customer qualifications proceed.
