ST10000NM014G Seagate Exos X18 10TB SAS 256 MB 3.5" Server HDD

High-Performance 3.5in SAS Enterprise Capacity HDD featuring helium-sealed CMR durability with the ST10000NM014G

The ST10000NM014G is engineered for data centre nearline tiers where modern CPU platforms and dense storage servers require predictable latency, consistent throughput, and controlled rebuild behaviour. In mixed virtualization and backup environments, its CMR recording model supports stable write performance under sustained queue depth, while the SAS link integrates cleanly into dual-controller backplanes and expander-based topologies commonly used in rack servers and storage arrays.

Designed for 24x7 hot-swap bays, the ST10000NM014G aligns with PCIe-attached HBA and RAID architectures by providing a dependable capacity layer behind compute nodes, including AI and analytics pipelines that stage datasets from bulk storage to NVMe. Advanced Format flexibility (512e or 4Kn) helps standardize sector sizing across fleets, and enterprise data integrity features reduce the risk profile during parity operations, long sequential transfers, and large-scale replication.

Why Choose the ST10000NM014G?

The ST10000NM014G delivers a practical density-to-performance balance for capacity tiers, combining helium-sealed mechanics with enterprise protection features for predictable operation in multi-drive enclosures. With SED capability and Instant Secure Erase, the ST10000NM014G supports scalable deployment where secure lifecycle handling, controlled decommissioning, and consistent fleet governance are mandatory.

Seagate designs the Exos platform with a reliability-first philosophy, emphasizing sustained duty cycles, firmware tuned for array environments, and qualification against modern data centre operating profiles. The ST10000NM014G reflects this approach through enterprise SAS integration, integrity mechanisms such as T10 DIF/Protection Information, and power management features suited to large drive counts.

Key Applications:

• Nearline capacity tiers in data centres
• Storage arrays and SAS JBOD expansion
• Backup repositories and recovery vaults
• Bulk archival and compliance retention
• Cold data staging for analytics pipelines
