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

The Seagate Exos X20 is an internal enterprise hard drive engineered for large-scale data center applications and cloud storage. It provides a 20 TB capacity within a standard 3.5-inch form factor, suitable for high-density servers and NAS systems. The drive utilizes a SAS interface operating at 12 Gbit/s to support the high-throughput data transfers required in demanding, always-on environments. Its construction is optimized for consistent performance and reliability in multi-drive arrays.

Performance is supported by a 7200 RPM spindle speed and a 256 MB cache, which help deliver sustained data transfer rates for intensive workloads. This model achieves sequential read and write speeds of up to 285 MB/s and 272 MB/s, respectively. It is rated for a Mean Time Between Failures (MTBF) of 2.5 million hours, reflecting its design for continuous operation. Integrated rotational vibration sensors maintain consistent performance in rack-mounted chassis by mitigating vibration from adjacent drives.
