ST24000NM005H Seagate Exos X24 24TB SAS 512 MB 3.5" Server HDD

High-Density 3.5in Nearline Enterprise HDD featuring dual-port SAS availability with the ST24000NM005H

The ST24000NM005H is a 24TB Seagate Exos X24 nearline HDD designed for scale-out storage nodes, JBOD shelves, and backup repositories where capacity-per-rack and predictable latency matter more than flash-tier IOPS. Its 7200 RPM CMR recording, 512MB cache, and helium-sealed mechanics are optimized for sustained sequential throughput and stable behavior under multi-drive vibration profiles typical of dense enclosures.

To integrate cleanly into modern server and storage platforms, the ST24000NM005H uses 12Gb/s SAS with dual-port connectivity, enabling redundant paths for high-availability designs across multipath HBAs and dual-controller arrays. Support for 512e and 4Kn sector formats eases alignment with legacy operating systems while enabling efficient, modern block sizing for object and file storage. Enterprise-grade data integrity features such as T10 Protection Information (PI) and RSA 3072 firmware signing help maintain end-to-end trust across controller, expander, and host layers.

Why Choose the ST24000NM005H?

The ST24000NM005H provides a pragmatic density-to-reliability profile for 24x7 datacenter operation, combining dual-path SAS resiliency with security controls that simplify compliance-driven decommissioning. It scales predictably in large pools, supports hot-plug service workflows, and reduces operational risk in HA architectures where link or controller failover must be nondisruptive.

Seagate engineers the Exos platform for continuous duty cycles with a focus on mechanical consistency, firmware robustness, and fleet manageability. With a 2.5M-hour MTBF target and power-aware operation, the ST24000NM005H aligns with enterprise data center standards for thermals, serviceability, and long-term availability planning.

Key Applications:

• Backup and archive repositories
• Object storage clusters
• Scale-out file storage
• JBOD capacity expansion
• Compliance-oriented secure retention
