Seagate Exos X22 3.5" 20TB, 7200 RPM, 512MB, SATA III Hard Drive, Enterprise

The Seagate Exos X22 ST20000NM004E is an enterprise-grade hard drive providing a 20 TB storage capacity, intended for large-scale data center and cloud environments. It operates on a SATA 6 Gb/s interface and is housed in a standard 3.5-inch form factor for broad compatibility with server and storage arrays. The drive's architecture is engineered for scalability in hyperscale applications that demand high-density storage solutions. Performance is facilitated by a 7200 RPM spindle speed and a 512 MB cache, which work together to manage data-intensive workloads and provide consistent throughput.

This model is constructed for continuous, 24/7 operation and supports a workload rate of up to 550 TB per year, making it suitable for demanding enterprise tasks. Its reliability is rated with a Mean Time Between Failures (MTBF) of 2.5 million hours, a key metric for critical storage systems. Integrated rotational vibration (RV) sensors help maintain consistent performance in dense multi-drive enclosures by mitigating vibration. The drive also supports hot-swapping, which enables replacement and maintenance without requiring system downtime, ensuring high availability.
