Seagate Exos 7E8 3.5" 4TB, 7200 RPM, 256MB, 550 WRL, SATA III Hard Drive, Enterprise

The Seagate Exos 7E8 ST4000NM000A is a 3.5-inch internal hard drive engineered for enterprise-level applications, including servers, network-attached storage (NAS), and RAID configurations. It provides 4 TB of storage capacity for bulk data and is built for continuous, 24/7 operation in demanding data center environments. The drive utilizes a SATA III interface for broad compatibility and features a 7200 RPM spindle speed, which works in conjunction with a 256 MB cache to facilitate consistent data access and transfer.

Designed for long-term reliability, this HDD has a Mean Time Between Failures (MTBF) of 2 million hours and is rated for a workload of up to 550 TB per year. It incorporates rotational vibration (RV) sensors to maintain steady performance in multi-drive systems by mitigating the effects of vibration. These features make it a suitable component for high-density storage arrays and workstations where data integrity and system uptime are critical operational requirements. The drive's power consumption during idle is rated at 5.38 W.
