The Seagate Exos X18 is an 18 TB internal hard drive engineered for high-capacity storage in enterprise environments. It utilizes a standard 3.5-inch form factor and a SATA 6 Gbit/s interface for broad compatibility with servers, workstations, and network-attached storage (NAS) systems. Designed for continuous operation, this drive is built to handle the demands of hyperscale cloud data centers and other intensive 24/7 workloads. Its construction incorporates rotational vibration sensors to maintain consistent performance in multi-drive arrays by mitigating the effects of system-induced vibrations.
Performance is delivered through a combination of a 7200 RPM spindle speed and a 256 MB cache, which facilitates efficient data processing and access. The drive achieves sustained data transfer rates of up to 270 MB/s for both read and write operations, suitable for large file transfers and data-intensive applications. Reliability is a key design aspect, reflected in its 2,500,000-hour Mean Time Between Failures (MTBF) rating and support for hot-swap functionality. The inclusion of end-to-end data protection helps ensure data integrity from the host to the drive.
