ST4000NM026B Seagate Exos 7E10 4TB SATA 256 MB 3.5" Server HDD

High-Performance 3.5in Enterprise HDD for capacity tiers and secure bulk storage with the ST4000NM026B

ST4000NM026B is a 4TB 3.5in internal enterprise HDD engineered for SATA-based server and storage platforms where CPU resources are allocated to RAID, NAS services, and data-management software rather than local compute acceleration. In typical x86 storage nodes and JBOD/RAID shelves, ST4000NM026B provides predictable latency and sustained throughput characteristics suited to 24x7 capacity tiers.

Using CMR recording at 7200 RPM with 256MB cache, ST4000NM026B maintains consistent write behavior under RAID rebuilds and parallel ingest, avoiding the variability often associated with shingled recording. The SATA interface aligns with dense backplanes and expanders while preserving broad compatibility across PCIe-attached HBA and RAID controller ecosystems. Support for 512e/4Kn with adjustable logical sector size enables correct alignment for modern filesystems and object stores, reducing write amplification and improving array efficiency in scale-out NAS and archival pools.

Why Choose the ST4000NM026B?

ST4000NM026B is selected when architectural priorities include controlled capacity density, operational continuity, and security at rest without introducing additional platform complexity. It supports scalable deployment patterns from small RAID groups to large NAS clusters, while a 2.0M hour MTBF target aligns with enterprise reliability expectations for always-on storage nodes.

Seagate designs the Exos family around data centre duty cycles, focusing on consistent behavior under vibration, sustained workloads, and power governance. With PowerChoice support and defined idle and operating power profiles, Seagate enables predictable thermal and power budgeting in multi-drive enclosures.

Key Applications:

• RAID arrays for capacity tiers
• Scale-out NAS storage nodes
• Backup and recovery repositories
• Compliance-oriented bulk storage
• Self-encrypting drive deployments
