ST2000NM018B Seagate Exos 7E10 2TB SAS 256 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SAS HDD featuring SED security and 24x7 duty design with the ST2000NM018B

The ST2000NM018B is a 2TB CMR enterprise hard drive built for SAS server backplanes and storage arrays where predictable latency and sustained throughput matter more than peak burst performance. In dual-controller architectures, its dual-port SAS design supports multipath connectivity, enabling resilient failover paths and consistent service levels in shared storage domains.

Designed to complement modern CPU-based storage stacks and RAID/HBA platforms, the ST2000NM018B aligns with PCIe-attached SAS controllers by delivering stable queue handling and sector-format flexibility for infrastructure standardisation. Support for 4Kn native and 512e logical formats simplifies migration and performance tuning across mixed fleets, while hardware-based SED encryption and Protection Information with T10 DIF help maintain end-to-end integrity for data at rest and in flight through the storage pipeline.

Why Choose the ST2000NM018B?

The ST2000NM018B is engineered for capacity-centric tiers where density, reliability, and operational consistency drive architecture decisions. With 24x7 ratings and a 2.0M-hour MTBF profile, it fits scale-out expansion strategies, backup repositories, and general-purpose enterprise volumes that must remain online while meeting governance requirements for encryption and integrity. For power-managed racks, the ST2000NM018B also supports PowerChoice/PowerBalance to help control idle and active consumption characteristics.

Seagate designs Exos-class drives around measurable reliability, fleet manageability, and compatibility with modern data centre standards. The ST2000NM018B reflects that focus with enterprise firmware behaviour, security primitives integrated at the drive level, and sustained operation within controlled thermal envelopes.

Key Applications:

• Server RAID and HBA-based storage
• Capacity-tier storage pools
• Backup and recovery repositories
• General-purpose enterprise file and block storage
• Encrypted data-at-rest deployments
