Seagate IronWolf Pro 16 TB 3.5" 7200 RPM 256 MB SATA internal hard drive

16 TB NAS hard drive for multi-bay RAID

This 16 TB 3.5 inch drive runs at 7,200 RPM with a 256 MB cache and SATA 6 Gb/s interface. It uses conventional magnetic recording for consistent 24x7 operation in commercial and enterprise network attached storage. Rotational vibration sensors and AgileArray firmware keep performance steady across multiple bays. The drive is built for always-on RAID environments.

Upgrade from lower-capacity or non-CMR drives

Moving to this 16 TB model adds raw capacity and the reliability of CMR technology over shingled recording alternatives. The 550 TB per year workload rating and 2.5 million hour MTBF mark the point where the jump pays off for growing NAS arrays. It replaces drives that cannot sustain heavy multi-user access or that lack time-limited error recovery for RAID. Builders who need more than 16 TB or a different interface will need another solution.

Sustained 24x7 workload handling

Under continuous load the drive maintains throughput with dual-plane balancing and rotational vibration compensation. IronWolf Health Management monitors drive behaviour and issues prevention, intervention and recovery recommendations. The package includes three years of Rescue Data Recovery Services for zero-cost recovery if data loss occurs. A five-year limited warranty covers the hardware for long-term deployment.
