Seagate Exos X20 3.5" 18TB, 7200 RPM, 256MB, SATA III Hard Drive, Enterprise

The Seagate Exos X20 is an enterprise-class hard drive engineered for mass-capacity data storage in large-scale data centers and server applications. With a substantial 18 TB capacity, this drive utilizes advanced recording technology to achieve high areal density and storage efficiency. Its design is focused on providing a scalable and cost-effective solution for cloud data centers and other high-volume server environments. The standard 3.5-inch form factor ensures broad compatibility with existing enterprise infrastructure.

Performance is delivered through a 7200 RPM spindle speed, a 256 MB cache, and a SATA 6 Gb/s interface, which together facilitate sustained data transfer rates of up to 285 MB/s. This model is built for operational reliability, supported by a Mean Time Between Failures (MTBF) rating of 2.5 million hours and integrated end-to-end data protection to maintain data integrity. It also includes hot-swap support, allowing for drive replacement in active systems without causing operational downtime, a key requirement for enterprise storage arrays.
