Technologies and Innovations

• CMR Recording: Conventional Magnetic Recording provides predictable performance during extended write operations, which is important for RAID arrays.

• Helium-Sealed Design: Enables high storage capacity within a standard 3.5" drive enclosure.

• AgileArray: Seagate firmware featuring dual-plane balance optimizes drive operation in multi-drive NAS systems.

• Time-Limited Error Recovery (TLER): Limits error recovery time to help prevent the drive from being unnecessarily dropped from a RAID array by the controller.

• Rotational Vibration (RV) Sensors: Compensate for vibrations in densely populated NAS enclosures and help maintain performance.

• IronWolf Health Management: Monitors drive health and provides recommendations for preventive measures and corrective actions before problems arise.

• Rescue Data Recovery Services: Includes three years of data recovery services in the event of drive failure or data corruption.

Description

Data volumes are growing faster than storage budgets, and that is where 28 TB of capacity in a single drive can make a difference. The Seagate IronWolf Pro ST28000NT002 is designed for NAS and RAID systems with multiple users, where drives operate continuously. CMR recording helps maintain predictable performance under sustained workloads. AgileArray, TLER, and RV sensors are designed to support reliable drive operation in multi-drive arrays. A workload rate of up to 550 TB per year and an MTBF of 2.5 million hours place this drive in the professional storage category rather than the consumer segment. IronWolf Health Management monitors drive health and supports timely intervention. Seagate also includes three years of Rescue Data Recovery Services and a five-year limited warranty. The drive is suitable for archives, video surveillance, media libraries, backup servers, and workflows involving large files. If you are building or expanding a NAS with 3.5" drive bays, this drive is a practical option for long-term data storage.

Suitable For

• NAS systems for home, office, and small to medium-sized businesses.

• RAID arrays with multiple drive bays.

• Video surveillance systems and long-term archives.

• Media and creative workflows, including video, photography, and 3D content.

• Backup and file servers.
