ST18000NE000 Seagate IronWolf Pro NAS HDD +Rescue 18TB SATA 256 MB 3.5" Server HDD

High-Capacity 3.5in SATA Enterprise HDD designed for 24x7 NAS and RAID tiers with the ST18000NE000

The ST18000NE000 is an 18TB 3.5in internal enterprise HDD engineered for multi-bay NAS appliances and dense RAID arrays where predictable latency and sustained throughput matter more than burst performance. In storage-centric platforms, it complements modern CPU generations by shifting cost-effective capacity to the SATA tier, keeping PCIe lanes and memory bandwidth reserved for compute, NVMe caching, and high-IOPS datasets.

ST18000NE000 uses CMR recording with 512e Advanced Format to support consistent rebuild behavior in large arrays and broad OS and controller compatibility. Its 7200 RPM spindle and 256MB cache are optimized for mixed sequential and transactional NAS traffic through NCQ, while S.M.A.R.T. telemetry improves fleet monitoring. PowerChoice power management assists with rack-level power planning, and WWN support simplifies drive identification across clustered storage and automated provisioning workflows.

Why Choose the ST18000NE000?

The ST18000NE000 delivers a balanced density-to-performance profile for scalable SATA capacity tiers, enabling higher usable TB per rack unit without forcing NVMe spend where it is not required. Designed for 24x7 duty cycles and rated at 1.2M hours MTBF, ST18000NE000 supports predictable operations in multi-bay enclosures, helping storage architects standardize on a single high-capacity SKU for growth, spares, and consistent RAID planning.

Seagate designs enterprise and NAS-class drives with an engineering focus on reliability under continuous load, comprehensive health reporting, and compatibility with modern data centre operational standards. Seagate validation targets sustained operation in vibration-prone multi-drive environments, aligning with common RAID controllers, NAS operating systems, and capacity-tier architectures.

Key Applications:

• High-capacity RAID arrays in NAS appliances
• Backup and archive repositories
• Bulk storage tiers for virtualized environments
• Media libraries and workstation datasets
