Seagate IronWolf Pro 3.5" 16TB, 7200 RPM, 256MB, 550 WRL, SATA III Hard Drive for NAS

This 3.5-inch hard disk drive is engineered for integration into high-workload NAS environments, providing 16 TB of storage capacity. The internal components are designed to support continuous 24/7 operation, making the unit suitable for commercial and business systems requiring consistent data availability. A Mean Time Between Failures (MTBF) of 2.5 million hours provides an assessment of reliability for long-term use in multi-bay setups.

The drive utilizes a SATA 6.0 Gbps interface and operates at 7200 RPM, supported by a 256 MB cache for managing frequent data requests. It achieves sequential read speeds of 600 MB/s and write speeds up to 270 MB/s. System stability is enhanced through the inclusion of Rotational Vibration (RV) sensors, which mitigate performance degradation in dense chassis environments, particularly in multi-drive systems. This unit sustains a maximum annual workload limit of 550 TB.
