ST4000NM000A Seagate Exos E 7E8 4TB SATA 256 MB 3.5" Server HDD

Enterprise 3.5-inch Nearline SATA HDD for Capacity Tiers and RAID Arrays with the ST4000NM000A

The ST4000NM000A is a 3.5-inch internal enterprise HDD designed for data centre bulk storage and nearline capacity tiers where predictable latency and sustained throughput matter more than flash-class IOPS. In dual-socket server platforms and dense JBOD shelves, the ST4000NM000A integrates cleanly behind modern SATA host bus adapters and RAID controllers, supporting consistent rebuild behavior and stable write characteristics under continuous duty cycles.

By using 4TB CMR recording and 512n sector formatting, the ST4000NM000A aligns with operating systems and storage stacks that require native 512B sectors without translation overhead, simplifying legacy compatibility and reducing sector-mapping edge cases in mixed fleets. The 7200RPM spindle and 256MB cache are optimized for sequential and mixed read/write patterns typical of backup repositories, log retention, and object storage nodes, while PowerChoice power management supports rack-scale energy governance without compromising availability targets.

Why Choose the ST4000NM000A?

The ST4000NM000A delivers a balanced density-to-performance profile for scale-out capacity design, enabling cost-efficient expansion of RAID groups and SATA-based storage pools. With an enterprise 24x7 duty-cycle focus, the ST4000NM000A supports operational continuity through long service intervals, predictable thermal behavior, and reliability engineering aligned to large-drive population deployments.

Seagate designs Exos-class HDDs around measurable endurance, environmental sensing, and integration discipline for standardized data centre operations. The ST4000NM000A benefits from platform-oriented validation, including power management controls and humidity monitoring, supporting consistent behavior across multi-vendor enclosures and enterprise lifecycle processes.

Key Applications:

• Data centre bulk storage tiers
• Nearline capacity expansion
• RAID arrays in 3.5-inch SATA servers
• JBOD shelves for scale-out storage
• Backup and archive repositories
