Seagate Exos 3.5" 4TB, 7200 RPM, 256MB, 550 WRL, SAS Hard Drive, Enterprise

The Seagate Exos 7E8 ST4000NM003A is an internal hard drive engineered for enterprise-level applications that require high-capacity bulk storage. With a standard 3.5-inch form factor and a capacity of 4 TB, it is designed for integration into servers and data center storage systems. The drive utilizes a SAS interface for connectivity, providing a high-speed data path suitable for demanding IT infrastructures and mission-critical operations.

This model operates at a spindle speed of 7200 RPM and is equipped with a 256 MB cache, which facilitates efficient data access and transfer operations. It is built for continuous 24/7 workloads, rated with a Mean Time Between Failures (MTBF) of 2 million hours and an annual workload limit of 550 TB. To ensure stable performance in dense, multi-drive environments, integrated rotational vibration (RV) sensors help mitigate the effects of system-induced vibration.
