Build dependable, high-capacity storage for your business or home network with the Seagate IronWolf Pro 4TB HDD. Designed for network-attached storage (NAS) systems, this professional hard drive is built to support demanding workloads, continuous operation and shared access to files across compatible systems.
With 4TB of storage, a 7200 RPM spindle speed and a SATA III interface, the IronWolf Pro provides a practical storage solution for businesses, creative professionals, small offices and users managing growing digital libraries.
4TB Storage Capacity
Store documents, business files, photographs, videos, backups and other important data in one dedicated drive. The 4TB capacity makes it suitable for expanding compatible NAS systems and creating additional storage space for teams or households.
Designed for NAS and 24/7 Operation
IronWolf Pro drives are engineered for NAS environments that may operate continuously. They are suitable for compatible multi-bay NAS systems, including configurations used for shared business storage, centralised backups and RAID arrays.
The drive's intended workload and system compatibility should be checked against your NAS manufacturer's requirements before installation.
7200 RPM Performance
The 7200 RPM rotational speed supports responsive access to stored data and makes this drive suitable for NAS workloads involving multiple users and frequent file access.
SATA III Connectivity
The SATA 6 Gb/s interface enables connection to compatible desktop systems, NAS enclosures and storage servers. Check your system's drive bay, SATA connection and supported drive capacity before purchasing.
CMR Recording Technology and 256MB Cache
The ST4000NT001 variant uses conventional magnetic recording (CMR), making it suitable for supported NAS and RAID applications. Its 256MB cache helps manage data access during everyday storage operations.
IronWolf Health Management and Vibration Protection
Compatible systems can use IronWolf Health Management to help monitor drive health and provide guidance for maintaining storage reliability. Rotational vibration sensors help manage vibration in multi-drive NAS enclosures.
Built for Professional Storage Workloads
For the ST4000NT001 model, Seagate specifies a workload rate limit of up to 550TB per year and a mean time between failures (MTBF) of 2 million hours. These are manufacturer reliability and workload ratings, not guarantees of an individual drive's lifespan.
The model also carries a 5-year limited warranty and includes 3 years of Rescue Data Recovery Services where eligible, subject to Seagate's terms and regional availability.
