ST4000NM001B Seagate Exos 7E10 4TB SAS 256 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SAS HDD featuring dual-port security and integrity with the ST4000NM001B

The ST4000NM001B is a 4TB 3.5in Seagate Exos 7E10 enterprise HDD engineered for 24x7 server and storage-array duty cycles where predictable latency, sustained throughput, and controlled failure domains matter more than peak IOPS. In modern CPU-dense platforms, the drive complements high-core-count compute nodes and RAID controllers by providing consistent CMR behavior and 512n formatting, reducing translation overhead and aligning with legacy and mixed OS estates.

In PCIe-based storage architectures, the ST4000NM001B typically sits behind a 12Gb/s SAS HBA or hardware RAID adapter, enabling deterministic expansion across SAS backplanes without consuming additional PCIe lanes per drive. Dual-port SAS supports redundant pathing for high-availability enclosures, while T10 DIF end-to-end data protection strengthens integrity across controller, expander, and media. For secure multi-tenant or regulated environments, the ST4000NM001B integrates SED encryption with FIPS 140-2 validation to simplify compliance workflows during drive replacement, decommissioning, and return logistics.

Why Choose the ST4000NM001B?

The ST4000NM001B is a practical building block for capacity tiers that must scale predictably across large SAS domains while maintaining enterprise reliability targets. Its dual-port topology improves service continuity in multipath designs, and its security and data-integrity features help standardize deployments across mixed RAID groups and archival repositories.

Seagate designs the Exos line with a focus on consistent firmware behavior, sustained 24x7 operation, and qualification for rack-scale airflow and vibration conditions, aligning with modern data centre operational standards and long lifecycle management.

Key Applications:

• RAID storage tiers in SAS JBODs
• Capacity-oriented virtualisation datastores
• Backup and archival repositories
• High-availability dual-path SAS backplanes
• Compliance-driven encrypted storage pools
