Seagate Exos X20 3.5" 20TB, 7200 RPM, 256MB, 550 WRL, SAS Hard Drive, Enterprise

The Seagate Exos X20 is a 3.5-inch internal hard drive engineered for enterprise-level data storage environments. It offers a 20 TB capacity, making it suitable for hyperscale data centers, high-capacity servers, and large-scale surveillance systems. The drive connects via a 12 Gb/s SAS interface, designed to support the high-throughput requirements of modern server and workstation applications. Its primary function is to provide reliable, high-density storage for bulk data and cloud-based infrastructures.

Performance is driven by a 7200 RPM spindle speed and a 256 MB cache, which facilitate efficient data retrieval and transfer operations. The drive is built for sustained use, supporting a workload rate of 550 TB per year and continuous 24/7 operation. A Mean Time Between Failures (MTBF) rating of 2.5 million hours underscores its design for long-term reliability in demanding, always-on environments. Integrated rotational vibration (RV) sensors help maintain consistent performance in dense, multi-drive systems.

This model incorporates Self-Encrypting Drive (SED) technology to provide hardware-based data security, which helps protect sensitive information at rest without impacting performance. It also features end-to-end data protection to ensure data integrity from the host to the drive. These features make it a suitable component for enterprise storage solutions where data security and operational stability are critical requirements.
