Seagate IronWolf Pro ST12000NT001 12 TB NAS Hard Drive

The Seagate IronWolf Pro ST12000NT001 is a high-capacity, 3.5-inch internal hard drive engineered for demanding NAS environments. Built to deliver reliable, sustained performance in 24x7 workloads, this drive is purpose-built for commercial and enterprise multi-bay NAS storage solutions that serve multiple users and multiple applications simultaneously. With a focus on NAS optimization, AgileArray technology, and robust reliability, the IronWolf Pro 12 TB drive is designed to keep your data accessible,Secure, and flowing smoothly across your networked storage infrastructure. Whether you’re backing up critical business data, streaming media to a busy office, or hosting virtual machines, this drive provides the capacity, stability, and compatibility you need to keep a busy NAS running efficiently.

• Optimized for NAS with AgileArray – Built to thrive in multi-drive NAS environments, the IronWolf Pro benefits from AgileArray technology that combines enhanced RAID optimization, dual-plane balancing, and drive firmware tuned for sustained NAS performance. This results in improved data integrity, more predictable performance under heavy workloads, and smoother blue-sky operations for teams that rely on constant access to shared files.
• Massive 12 TB of scalable storage – Designed to scale with growing data needs, this 12-terabyte capacity provides ample room for large media libraries, backups, virtualization storage, and complex multi-user databases. With ample headroom for growth, you can consolidate multiple workloads into a single reliable NAS volume, reducing the need for frequent upgrades while maintaining fast access times for concurrent users and applications.
• Conventional Magnetic Recording (CMR) for reliability under load – The Seagate IronWolf Pro ST12000NT001 uses CMR technology to deliver consistent write performance during sustained workloads. CMR helps maintain predictable throughput in multi-user NAS setups, minimizing performance dips during intense file transfers, large backups, or heavy read/write operations common in office environments and media servers.
• 3.5-inch internal SATA drive with SATA/600 interface – This HDD fits standard 3.5-inch drive bays and uses a SATA 6 Gb/s (SATA/600) interface for wide compatibility with NAS enclosures, servers, and workstations. The broad compatibility makes it easy to integrate with a wide range of NAS platforms and PC storage systems, enabling straightforward upgrades without changing existing hardware configurations.
• Reliability for 24x7 NAS workloads in multi-bay configurations – Engineered for continuous operation in busy storage environments, the IronWolf Pro is built to handle high-demand NAS use cases, including multi-user access, multi-application workloads, and large-scale backups. Its design supports multiple bays and ensures steady performance, even as dataset sizes grow and teams collaborate more intensively on shared storage.
