About the Seagate ST20000NT001 20TB SATA 6Gb/s - Seagate IronWolf Pro NAS
A 20TB capacity drive spinning at 7200 RPM defines this drive's placement in the enterprise NAS tier. The Seagate IronWolf Pro (model ST20000NT001) is purpose-built for multi-bay NAS enclosures where reliability, sustained throughput, and high workload tolerance are non-negotiable. Storage architects and IT procurement teams standardizing on Seagate solutions will find this drive delivers the density and performance characteristics required for medium-to-large scale networked storage deployments.
This Seagate drive employs CMR recording technology and connects via SATA 6Gb/s in a 3.5-inch form factor, integrating seamlessly into existing NAS infrastructure. The 256MB cache buffer and 7200 RPM spindle speed support sustained data movement typical of backup, archival, and collaborative workloads. With an annualized workload rate of 300TB/year and an MTBF rating of 1,200,000 hours, the IronWolf Pro targets environments where continuous availability outweighs the cost per terabyte. Operating across a 0°C to 70°C temperature window, power consumption of 7.8W during random read/write operations and 5.0W at idle keeps thermal and electrical loads predictable in densely populated enclosures.
