ST4000NM000B Seagate Exos 7E10 4TB SATA 256 MB 3.5" Server HDD

High-Density 3.5-inch Enterprise SATA HDD for Capacity Storage Nodes with the ST4000NM000B

The ST4000NM000B is a 4TB Seagate Exos 7E10 3.5-inch internal enterprise HDD engineered for capacity-centric server platforms where predictable throughput and continuous duty cycles matter more than low-latency flash. In mixed CPU environments and virtualised storage stacks, the ST4000NM000B supports consistent streaming I/O for bulk datasets while keeping per-bay cost and power envelope aligned to dense rack deployments.

Designed for SATA backplanes and HBA/RAID-controller architectures commonly connected via PCIe, the ST4000NM000B integrates cleanly into capacity-optimised RAID arrays and scale-out storage nodes. CMR recording behaviour helps maintain stable rebuild characteristics under sustained write pressure, while the 7,200 RPM spindle and 256MB cache support balanced sequential performance for backup windows and repository ingestion. With 512n sector formatting, the ST4000NM000B reduces translation overhead in legacy and appliance environments that require native 512B sectors for predictable compatibility.

Why Choose the ST4000NM000B?

The ST4000NM000B targets enterprise fleets that need reliable 24x7 bulk capacity with controlled operational risk. Its 3.5-inch density profile supports scalable growth in multi-bay chassis, and the ST4000NM000B aligns well with RAID and erasure-coded designs where drive consistency, service life, and repeatable performance under load are critical for storage SLA planning.

Seagate designs the Exos line around data centre operating discipline, focusing on predictable behaviour, thermal tolerance, and long-life reliability. With an MTBF rating of 2.0M hours, the ST4000NM000B reflects an engineering approach intended for continuous operation in modern racks, standard hot-swap bays, and managed storage nodes.

Key Applications:

• Server bulk storage
• Capacity-optimised RAID arrays
• Backup repositories
