Seagate Launches 44TB Hard Drives with Mozaic 4+ HAMR Platform
Event summary
- Seagate's Mozaic 4+ platform, the industry's only heat-assisted magnetic recording (HAMR)–based storage platform deployed at-scale, is now qualified and in production with two leading hyperscale cloud providers.
- The platform supports capacities up to 44TB, with additional customer qualifications underway.
- Seagate aims to scale from today’s 4TB per-disk toward a future 10TB per-disk, enabling hard drive capacities of up to 100TB.
- The platform incorporates a next-generation suspension architecture and an enhanced system-on-a-chip for precise recording at higher densities.
- Seagate’s custom-designed and manufactured laser technology reflects years of investment in nanophotonic engineering.
The big picture
Seagate's Mozaic 4+ platform addresses the growing need for scalable, efficient, high-performance storage solutions in the era of AI-driven data growth. The platform's ability to support capacities up to 44TB and its vertically integrated photonics technology position it as a critical component in data center infrastructure. The strategic anomaly here is the rapid adoption by hyperscale cloud providers, underscoring the platform's critical role in managing ever-increasing data volumes and maximizing returns on investments in today’s AI-driven world.
