Seagate ST4000NM0025 – 4TB Enterprise SAS 12 Gb/s Hard Drive

Overview

The Seagate ST4000NM0025 is a 4 TB enterprise‑class internal hard drive designed for data centers, storage servers, and multi‑drive RAID arrays where high capacity and sustained throughput are required. It targets IT engineers and storage architects deploying bulk storage solutions with reliability demands for 24 × 7 operation.

This drive supports a 12 Gb/s SAS interface with a 3.5‑inch form factor and a 7200 RPM spindle speed, delivering reliable random and sequential performance across heavy workloads. Its 128 MB cache helps maintain consistent data streams in dense storage environments.

Built for nearline enterprise applications, it integrates easily into replicated and RAID bulk storage servers and SANs. Its design meets high workload ratings and incorporates vibration tolerance for stable multi‑drive performance.

Use this model in systems with SAS controllers and backplanes designed for enterprise storage. It is not intended as a consumer or desktop SATA drive; proper SAS support is required for full functionality.
