- Seagate Exos 4U100 delivers multi-petabyte capacity for demanding AI and ML workflows
- HAMR technology powers the Exos 4U100’s density and long-term storage durability
- Edge environments benefit from the Exos 4U100’s ability to ingest continuous data
Seagate has unveiled its new Exos 4U100 and 4U74 JBOD systems, designed to handle the rising data demands of artificial intelligence and machine learning.
The flagship Exos 4U100 enclosure delivers a maximum capacity of 3.2 petabytes, combining density and performance aimed at both data centers and edge environments.
Seagate’s Mozaic HAMR technology lies at the core of this release, engineered to support high-volume data throughput while reducing power consumption.
Innovation built for the edge
Seagate says its HAMR tech is capable of keeping pace with the scale and speed required in AI-driven workflows.
The company presents the Exos 4U100 as a solution for environments where data is generated and processed outside central cloud systems.
The system targets AI workloads which depend on rapid updates and local analysis and supports model checkpointing, long-term data retention, and continuous ingestion.
Seagate claims the Exos 4U100 achieves 70% more efficient cooling and consumes 30% less power than the previous generation, with flexibility for both SAS and SATA configurations.
However, as with all dense enclosures, efficiency claims will depend heavily on real-world workloads and how effectively systems maintain stability under sustained data operations.
SSDs dominate high-speed caching, and flash drives remain useful for mobility, however, HDD-based systems like the Exos 4U100 continue to offer unmatched capacity for long-term storage at a lower cost.
For AI workflows, where data is constantly generated, trained, and archived, such hybrid approaches are becoming critical.
The challenge lies not in raw capacity but in maintaining efficiency and security across diverse storage layers.
Seagate includes secure boot, Redfish management, and its proprietary Seagate Secure certification to protect against unauthorized access.
These safeguards are essential as data sovereignty regulations and privacy expectations evolve.
Yet, while security is emphasized, the question remains whether such large enclosures can remain manageable within fast-changing AI environments.
The Exos 4U100 represents Seagate’s confidence in mechanical storage’s continued relevance even as SSD and flash technologies advance.
“The Seagate Exos 4U100 JBOD marks the beginning of a bold new chapter in edge storage innovation—engineered to meet the evolving demands of data creation, storage, replication and analysis at the edge,” said Melyssa Banda, SVP Edge Storage and Services at Seagate.
