Seagate's New Storage Looks to Cover Everything You'll Need for the Age of AI - Including up to 3.2 Petabytes in a Single Enclosure

Why It Matters

By offering petabyte‑scale, power‑efficient HDD capacity at the edge, Seagate gives AI developers a lower‑cost alternative to all‑flash arrays, potentially reshaping storage architectures for data‑intensive machine‑learning workloads.

Summary

Seagate announced its Exos 4U100 and 4U74 JBOD systems aimed at AI and edge workloads, with the flagship 4U100 delivering up to 3.2 petabytes of capacity in a single 4‑U enclosure. The systems leverage Seagate’s Mozaic HAMR technology and support both SAS and SATA drives, promising 70 % more efficient cooling and 30 % lower power consumption versus the prior generation. Built for rapid model checkpointing, continuous ingestion and long‑term retention, the enclosures include secure boot, Redfish management and Seagate Secure certification. The launch underscores Seagate’s push to keep high‑density mechanical storage relevant alongside flash solutions for massive AI data pipelines.
