About the Seagate ST12000NM002H 12TB 3.5-inch SATA Enterprise HDD
With a 256MB cache buffer and sustained transfer rate of 261MB/s, the Seagate ST12000NM002H delivers the performance and capacity balance required for backup, NAS, and archive deployments. This 12TB, 3.5-inch SATA enterprise drive operates at 7200 RPM and uses helium-sealed technology to reduce friction and enhance reliability in mission-critical storage environments. The ST12000NM002H belongs to Seagate's Exos X18 series, engineered specifically for demanding data center workloads where uptime and throughput matter equally.
Storage architects and IT procurement teams choose this drive for its proven endurance metrics: an MTBF of 2,500,000 hours, an annualized failure rate of just 0.35%, and a rated workload of 550TB per year ensure consistent performance across large-scale deployments. Operating at 9.0W during read/write cycles and 5.0W at idle, the Seagate enterprise HDD minimizes power overhead in multi-bay systems. The SATA 6Gb/s interface integrates seamlessly into existing infrastructure, while the 512e sector format (with optional 4Kn support) maintains compatibility with legacy and modern storage controllers alike. Temperature tolerance ranging from 0°C to 60°C covers standard data center conditions, and both operating and non-operating shock ratings (70G and 200G respectively) protect against facility vibration and transportation stress.
