From 4TB per platter to a 100TB roadmap
Seagate’ s Mozaic platform, based on HAMR( Heat-Assisted Magnetic Recording), now enables capacities of up to 4TB per platter. That density is already supporting 44TB drives, with Seagate targeting a roadmap to 100TB hard drives in the future.
The impact goes beyond raw capacity. Fewer drives mean fewer enclosures, lower networking complexity, reduced power draw and improved racklevel efficiency. Instead of building additional white space, operators can continue scaling within existing infrastructure.
This is a critical shift for AI-era workloads, where data growth is outpacing the ability of many facilities to expand physically. Higher-capacity drives can reduce embodied carbon and operational costs by lowering the number of systems required per exabyte stored.
2.5PB in a single 4U chassis
Those density gains are also reflected in Seagate’ s Exos storage systems. The Seagate Exos CORVAULT 4U106 platform delivers up to 2.5PB in a compact 4U chassis, designed for large-scale data environments. Integrated self-healing technologies and autonomous drive management help improve resilience while reducing maintenance overhead.
For data-centre operators, the conversation is increasingly about efficiency per rack rather than simply adding more racks. Seagate’ s roadmap suggests that future-ready storage will be defined by how much capacity can be delivered within the infrastructure already in place.
