Seagate Technology has unveiled its next-generation Mozaic™ 4+ storage platform, introducing the industry’s highest-capacity hard drives aimed at meeting the rapidly rising storage needs driven by artificial intelligence and large-scale cloud computing. The company said the Mozaic 4+ platform, based on heat-assisted magnetic recording (HAMR) technology, is currently the only HAMR-based storage platform deployed at scale. The platform supports hard drive capacities of up to 44TB and has already been qualified and moved into production with two leading hyperscale cloud providers.
According to Seagate, the platform integrates a next-generation suspension architecture and an enhanced system-on-a-chip, enabling precise recording at higher densities while maintaining enterprise-class reliability. The company is working toward scaling from 4+TB per disk to a future 10TB per disk, which could allow hard drive capacities of up to 100TB. “Data has become one of the most valuable assets for enterprises,” said Dave Mosley, Seagate’s chair and chief executive officer, noting that the company’s HAMR-based Mozaic products provide the scale, performance and efficiency required to unlock the full potential of data in an AI-driven world.
Seagate said its vertically integrated photonics technology, including custom-designed nanophotonic lasers used in HAMR recording, strengthens manufacturing control, improves reliability and enhances supply-chain resilience while supporting predictable production economics. In Kolkata, technology distributors and enterprise IT solution providers believe demand for high-capacity storage solutions is increasing as companies expand AI, cloud infrastructure and data analytics operations. Industry players say businesses in Kolkata, including IT service firms and data-centre operators, are gradually adopting large-scale enterprise storage platforms to manage rapidly growing volumes of digital data.
