Built for bulk-data workloads

The Seagate Enterprise Capacity 3.5-inch drive delivers 3TB of storage on a SATA 6.0Gb/s interface. It uses conventional magnetic recording with a 128MB cache and spins at 7200 RPM. Designed for 24x7 operation in multi-drive servers and storage arrays, it targets cloud infrastructures, hyperscale deployments and centralized surveillance systems that need reliable capacity density.

Sustained throughput in dense arrays

The drive is engineered for workloads of 550TB per year, ten times the rating of desktop drives. Advanced Write Caching applies enhanced algorithms to maintain consistent performance across replicated and RAID configurations. Dual processors and ramp-load technology help sustain data access during continuous read and write cycles without the short-term bursts that characterize consumer workloads.

Cool, quiet 24x7 operation

A top-cover-attached motor and humidity sensor contribute to stable thermals in fully populated chassis. The 512n sector format and industry-standard 3.5-inch dimensions (26.10mm height, 101.85mm width, 147.00mm length) allow efficient airflow in dense enclosures. Power efficiency is optimized for always-on environments, supporting reliable operation with minimal acoustic impact.
