ST24000NM001H Seagate Exos X24 24TB SATA 512 MB 3.5" Server HDD

High-Density 3.5in Enterprise Nearline HDD featuring helium-sealed CMR architecture with the ST24000NM001H

The ST24000NM001H is a 24TB 3.5in internal enterprise HDD engineered for capacity-driven server and JBOD tiers where SATA connectivity, predictable latency, and 24/7 duty cycles are required. Deployed behind modern CPU platforms and storage controllers, the drive aligns well with high-core-count virtualization hosts and scale-out storage nodes that need consistent sequential throughput without the cost or lane pressure of PCIe/NVMe expansion.

With CMR recording and a helium-sealed mechanical design, ST24000NM001H supports RAID rebuild behavior and sustained write patterns that are typical in backup repositories and object storage. Its 512MB cache helps smooth bursty metadata and mixed read/write activity, while 512e and 4Kn sector format support simplifies integration into heterogeneous storage pools and OS images. For security-focused architectures, the ST24000NM001H implements Self-Encrypting Drive hardware encryption to reduce CPU overhead versus software-based encryption and to support controlled decommissioning workflows.

Why Choose the ST24000NM001H?

The ST24000NM001H provides a practical density-to-bay ratio for nearline capacity expansion, enabling fewer spindles per usable terabyte and more efficient power and rack planning. Built for enterprise reliability with a 2.5M hour MTBF, the ST24000NM001H scales cleanly from single servers to multi-shelf JBOD deployments, supporting hot-plug serviceability and standardized SATA operational processes.

Seagate designs the Exos platform with an engineering focus on predictable behavior under sustained workloads, compatibility with common HBA/RAID controller stacks, and durability aligned with modern data centre service models. The ST24000NM001H reflects this approach through consistent 7200 RPM performance characteristics, controlled thermals across 10–60C, and security features intended for governed storage estates.

Key Applications:

• High-density JBOD capacity expansion
• Backup and restore repositories
• Object storage nodes and data lakes
• Enterprise RAID arrays
• Nearline archival tiers
