Seagate IronWolf 3.5" 4TB, 5900 RPM, 64MB, SATA III Hard Drive for NAS

The Seagate IronWolf ST4000VN008 is a 4 TB internal hard drive designed specifically for continuous operation within multi-bay network-attached storage (NAS) systems. Its 3.5-inch form factor is standard for desktop, server, and dedicated NAS enclosures. The drive integrates AgileArray technology, which provides firmware optimizations to enhance performance and reliability in multi-user RAID environments. This HDD is constructed for 24/7 availability, making it suitable for private cloud storage, media servers, and collaborative file sharing.

Data transfer is handled via a SATA 6 Gbit/s interface, supported by a 5900 RPM spindle speed and a 64 MB cache. To maintain performance integrity in multi-drive configurations, integrated Rotational Vibration (RV) sensors actively mitigate vibration. This model is rated for a workload of up to 180 TB per year and has a Mean Time Between Failures (MTBF) of 1 million hours. These specifications ensure consistent data throughput for functions such as media streaming, system backups, and data archiving.
