ST24000NM001K Seagate Exos M 24TB SATA 512 MB 3.5" Server HDD

High-Density 3.5in Nearline SATA Enterprise HDD with helium-sealed CMR architecture using the ST24000NM001K

The ST24000NM001K is a 24TB Seagate Exos M internal HDD designed to scale capacity in modern server and JBOD platforms where CPU and GPU resources are provisioned independently from storage growth. In data centre designs prioritising predictable throughput and low operational overhead, ST24000NM001K supports sustained sequential performance while maintaining stable latency characteristics for large-block transfers typical of backup targets and object storage nodes.

Architecturally, ST24000NM001K fits into SATA backplanes and standard 3.5in bays to maximise density per RU without consuming PCIe lanes that are reserved for accelerators, high-speed NICs, and NVMe tiers. The CMR recording method and 7200RPM spindle profile are tuned for consistent write behaviour under 24/7 duty cycles, while the 512MB cache helps smooth burst activity. With 4Kn media and 512e emulation, ST24000NM001K integrates cleanly with mixed-OS fleets and aligns with capacity-focused storage topologies where object, archive, and backup tiers sit behind compute clusters.

Why Choose the ST24000NM001K?

ST24000NM001K delivers a strong density-to-performance ratio for nearline pools, enabling straightforward scaling by adding bays rather than re-architecting the PCIe fabric. For enterprise reliability, ST24000NM001K targets continuous operations with a 2.5M-hour MTBF profile and includes Instant Secure Erase to support controlled decommissioning and security erase workflows in shared environments.

Seagate engineering for the Exos family emphasises predictable behaviour in multi-drive enclosures, helium-filled mechanics for efficiency, and platform features such as HAMR-based design elements and humidity sensor support to align with current data centre monitoring and lifecycle standards.

Key Applications:

• Scale-out object storage nodes
• Backup repositories
• Archive tiers
• JBOD capacity expansion
• Data retention and compliance storage
