Seagate IronWolf 3.5" 4TB, 5400 RPM, 256MB, SATA III Hard Drive for NAS

The Seagate IronWolf 4 TB hard drive is engineered specifically for use in network-attached storage (NAS) systems with one to eight bays. Its design prioritizes operational reliability in multi-drive configurations, making it a suitable component for home, SOHO, and small business environments. Integrated rotational vibration (RV) sensors help maintain consistent performance by mitigating vibration from adjacent drives in a shared enclosure. This HDD is constructed to handle the sustained demands of continuous, 24/7 data access and storage.

This model operates with a spindle speed of 5400 RPM and connects via a SATA III interface, which supports data transfer rates up to 6 Gbit/s. A 256 MB cache is included to facilitate efficient data handling and reduce latency during common read and write tasks. The combination of these specifications provides balanced performance for typical NAS workloads such as centralized file sharing, media streaming, and automated data backup. Its standard 3.5-inch form factor ensures physical compatibility with most desktop-style NAS enclosures and server chassis.
