======================================================================Seagate 
Exos 4U100 delivers multi-petabyte capacity for demanding AI and ML workflows 
HAMR technology powers the Exos 4U100s density and long-term storage 
durability Edge environments benefit from the Exos 4U100s 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. 

Seagates 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 Seagates confidence in mechanical storages 
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 innovationengineered 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.
