ST10000NM018B Seagate Exos 7E10 10TB SAS 256 MB 3.5" Server HDD

High-Density 3.5in Enterprise SAS Nearline HDD featuring dual-port HA storage with the ST10000NM018B

The ST10000NM018B is a 10TB 3.5in enterprise SAS HDD engineered for capacity-optimised server storage where CPU and GPU resources are shared across many tenants and data services, and storage must remain predictable under 24x7 mixed read/write profiles. In modern x86 virtualization and container platforms, this drive complements DDR4/DDR5 memory architectures by keeping large datasets close to compute while controlling $/TB and rebuild exposure in dense shelves.

For PCIe-centric systems, the ST10000NM018B fits cleanly behind SAS HBAs or RAID controllers in PCIe Gen3/Gen4 slots, enabling scalable expansion without consuming NVMe lanes reserved for latency-sensitive tiers. Its CMR media supports consistent write behavior for RAID and erasure coding, while Advanced Format 512e/4Kn options align with OS and filesystem standards. Dual-port SAS connectivity is designed for redundant paths in HA backplanes, and the integrated SED hardware encryption supports secure decommissioning and compliance without host CPU overhead.

Why Choose the ST10000NM018B?

The ST10000NM018B provides a practical density-to-performance balance for nearline tiers, pairing 7200 RPM behavior with enterprise availability features suited to scale-out NAS/SAN and shared storage arrays. With dual-port pathing, T10 DIF support, and an MTBF rating of 2.0M hours, the ST10000NM018B is positioned for predictable operations, faster fault isolation, and scalable deployment across multi-shelf architectures.

Seagate designs Exos-class drives with a focus on sustained 24x7 duty cycles, data integrity controls, and interoperability with common storage backplanes and controllers. The platform engineering behind the ST10000NM018B targets enterprise qualification expectations, including secure-by-design options and alignment with standard sector formats used in modern data centres.

Key Applications:

• Capacity-optimised server storage
• Scale-out NAS/SAN nearline tiers
• Backup and archive repositories
• Content repositories
• 24x7 mixed read/write enterprise arrays
