Seagate ST4000NM0115 4TB 7200 RPM 128MB 512e SATA 3.5" internal hard drive

Enterprise bulk storage

The Seagate Enterprise Capacity 3.5 drive delivers 4TB of storage on a SATA interface using conventional magnetic recording technology. It is built for 24x7 workloads rated at 550TB per year, far above typical desktop limits. The 128MB cache and 7200 RPM spindle speed support sustained throughput in multi-drive arrays. This drive suits administrators who need dense, reliable capacity for bulk-data applications.

SATA integration for RAID servers

A standard 3.5-inch form factor with 512e sector formatting allows direct installation into hot-swap bays and backplanes designed for SATA 6Gb/s or 12Gb/s SAS connectivity. Dual processors and ramp-load mechanics maintain consistent performance when drives are packed tightly in replicated or RAID configurations. No special mounting hardware or controller features beyond the standard SATA interface are required for integration.

Thermal design for continuous operation

Top-cover-attached motor and humidity sensor help the drive operate reliably across varied chassis airflow conditions. Advanced Write Caching algorithms optimise workload efficiency to reduce unnecessary mechanical activity during sustained writes. The 4.16ms average latency reflects steady rotational performance under enterprise duty cycles. Power draw and acoustics remain stable during round-the-clock operation in dense storage enclosures.
