About the Seagate ST20000NM007H 20TB 3.5-inch SATA Enterprise HDD
Operating at just 5.0W during idle and 9.0W under read/write loads, the Seagate ST20000NM007H delivers exceptional power efficiency for large-scale storage deployments where every watt compounds across hundreds of drives. This 20TB enterprise-class HDD is engineered for storage architects and IT procurement teams building cost-effective, high-density JBOD systems that demand reliability without excessive power overhead.
The Seagate Exos X20 series represents a mature platform for mission-critical workloads up to 550TB/year. With Conventional Magnetic Recording (CMR) technology, a helium-sealed enclosure, and proven enterprise-grade construction, this drive combines predictable performance with exceptional longevity. An MTBF rating of 2,500,000 hours and annual failure rate of just 0.35% reflect Seagate's commitment to uptime in data center environments. The drive sustains 285MB/s throughput and maintains non-recoverable read error rates at 1 per 10^15 bits read—metrics that matter when data integrity is non-negotiable. Built to specification ST20000NM007H, this 3.5-inch SATA drive slots seamlessly into existing infrastructure while delivering 20TB of formatted capacity in a compact footprint.
