- Seagate Exos 4U100 delivers multi-petabyte capacity for demanding AI and ML workflows
- HAMR technology drives 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 increasing 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 center and edge environments.
Seagate’s Mozaic HAMR technology is at the heart of this release, engineered to support high-volume data throughput while reducing power consumption.
Innovation built to the edge
Seagate says its HAMR technology is capable of keeping up 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 of central cloud systems.
Targeting AI workloads that depend on fast updates and local analysis, the system supports model checkpointing, long-term data storage, and continuous ingestion.
Seagate claims the Exos 4U100 achieves 70% more efficient cooling and uses 30% less power than the previous generation, with flexibility for both SAS and SATA configurations.
However, as with all tight enclosures, efficiency requirements will depend heavily on real-world workloads and how effectively the systems maintain stability under sustained data operation.
SSDs dominate high-speed caching and flash drives remain useful for mobility, but HDD-based systems like the Exos 4U100 continue to offer unmatched capacity for long-term storage at a lower price.
For AI workflows where data is constantly generated, trained and archived, such hybrid approaches become critical.
The challenge is not in raw capacity, but in maintaining efficiency and security across different 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.
But while security is emphasized, the question remains whether such large enclosures can remain manageable in rapidly changing AI environments.
The Exos 4U100 represents Seagate’s confidence in mechanical storage’s continued relevance even as SSD and flash technologies evolve.
“Seagate Exos 4U100 JBOD marks the beginning of a bold new chapter in edge storage innovation – engineered to meet the changing demands of data creation, storage, replication and analytics at the edge,” said Melyssa Banda, SVP Edge Storage and Services at Seagate.
