ST12000NM007J
High-Density 3.5in Enterprise SAS HDD for secure nearline capacity with the ST12000NM007J
The ST12000NM007J is a 12TB Seagate Exos X18 enterprise HDD engineered for 24x7 server and storage array duty cycles where predictable latency, strong streaming throughput, and strict data governance are required. As a 12Gb/s SAS dual-port device, it fits cleanly into modern RAID and shared-storage backplanes, enabling multipath high availability and simplified serviceability in clustered architectures.
With CMR recording and a helium-sealed 3.5in platform, the ST12000NM007J targets bulk capacity tiers that must remain performant under sustained sequential and mixed workloads. Support for 512e and 4Kn logical sector formats helps align the drive with OS, HBA, and array formatting strategies, while T10 DIF strengthens end-to-end data integrity for enterprise SAS fabrics. For regulated environments, the ST12000NM007J integrates hardware self-encrypting drive capabilities with FIPS 140-2 / 140-3 certified encryption to reduce operational risk without adding host CPU overhead.
Why Choose the ST12000NM007J?
The ST12000NM007J delivers a balanced density-to-reliability profile for nearline RAID and SAS SAN/NAS deployments, combining dual-port SAS resiliency with enterprise-class integrity and encryption controls. This makes the ST12000NM007J a practical building block for scalable capacity expansion where failure-domain planning, consistent drive behavior, and secure decommissioning are non-negotiable.
Seagate designs the Exos family around data center operational discipline, focusing on deterministic performance, long service life, and compatibility with standardized SAS infrastructure. The ST12000NM007J is validated for continuous operation, supported by a 2.5M hours MTBF target, and optimized for dense enclosures with efficient power characteristics and controlled thermals across 5–60°C.
Key Applications:
- RAID-based nearline storage pools
- SAS SAN and enterprise NAS tiers
- Data center bulk capacity archives
- Secure and regulated data retention
- High-availability dual-controller storage arrays
