SATA 6Gb/s 3.5-inch enterprise HDD with 1,200,000-hour MTBF — the Seagate ST18000NT001 IronWolf Pro NAS drive delivers 18TB of capacity purpose-built for always-on network storage environments. Engineered by Seagate for multi-bay NAS systems supporting up to 24 bays, this drive combines high workload tolerance with proven reliability in demanding data center deployments. The 256MB cache buffer and 272 MB/s maximum sustained transfer rate ensure responsive performance across concurrent user access patterns, while the 7200 RPM spindle maintains consistent throughput for mission-critical applications.
Designed for storage architects and IT procurement teams managing enterprise NAS infrastructure, the ST18000NT001 rated for 300TB annual workload and 600,000 load/unload cycles maximizes uptime in continuous operational settings. CMR recording technology provides predictable performance and compatibility with standard NAS platforms, while Rotational Vibration (RV) sensors minimize mechanical interference in densely populated storage arrays. Operating across 0°C to 70°C conditions with just 7.8W read/write consumption and 5.0W idle draw, this Seagate drive balances thermal efficiency with enterprise-grade endurance specifications.
