Seagate IronWolf Pro 3.5" 4TB, 7200 RPM, 256MB, SATA III Hard Drive for NAS

The Seagate IronWolf Pro is a 4 TB internal hard drive engineered for continuous operation in multi-bay Network Attached Storage (NAS) systems. It is built for the demands of small-to-medium enterprise (SME) and SOHO environments, supporting a workload rate of 300 TB per year. The drive is rated for 24/7 accessibility, providing a reliable storage foundation for collaborative projects and centralized data archiving. Its firmware is specifically optimized for NAS enclosures, incorporating features for power management and error recovery control to ensure system stability.

This 3.5-inch drive operates at a spindle speed of 7200 RPM and includes a 256 MB cache to facilitate efficient data retrieval and sustained transfer rates up to 200 MB/s. Integrated Rotational Vibration (RV) sensors help maintain consistent performance by mitigating vibration common in systems populated with multiple drives. The SATA III interface provides a connection bandwidth of up to 6 Gbit/s, while drive health can be monitored using S.M.A.R.T. technology to anticipate potential issues. It is validated for use in NAS configurations containing up to 24 drive bays.
