ST4000NM0014 Seagate Enterprise Capacity 4TB SAS 128 MB 3.5" Server HDD

High-Density 3.5-inch Enterprise SAS HDD for 24x7 Storage Tiers with the ST4000NM0014

The ST4000NM0014 is a 3.5-inch enterprise HDD engineered for predictable latency and sustained throughput in server and storage platforms where CPU and memory resources are optimized for capacity-centric data services rather than compute acceleration. In typical dual-socket x86 nodes, the ST4000NM0014 complements modern memory hierarchies by keeping hot metadata in RAM while delivering economical bulk capacity for cold and warm datasets, backup chains, and log retention.

Designed for 12Gb/s SAS backplanes, the ST4000NM0014 integrates cleanly into RAID controllers and SAS expanders across PCIe-based storage subsystems, enabling dense JBOD shelves and SAN-attached pools without redesigning the host I/O topology. Its CMR media behavior and 4Kn sector format support consistent rebuild characteristics and aligned I/O for contemporary filesystems and object layers, while 7200RPM performance targets mixed sequential and moderate random access patterns in scale-out storage nodes.

Why Choose the ST4000NM0014?

The ST4000NM0014 delivers a balanced density-to-performance profile for enterprise arrays where reliability, serviceability, and predictable behavior under continuous duty cycles matter more than peak benchmarks. With 24/7 qualification and a 2.0M hour MTBF rating, the ST4000NM0014 is well-suited to scalable deployments that require repeatable fleet characteristics across large RAID sets and multi-shelf growth.

Seagate designs enterprise HDDs with an emphasis on controlled firmware behavior, validation against common SAS infrastructure, and sustained operation in thermally constrained racks. This engineering approach aligns with modern data centre standards for availability, maintenance windows, and long-lived storage tiers.

Key Applications:

• Data centre bulk storage
• RAID arrays in servers and storage systems
• SAN and JBOD expansion shelves
• Backup and archive tiers
• Scale-out file and object storage nodes
