Seagate Exos X18 3.5" 12TB, 7200 RPM, 256MB, SAS Hard Drive, Enterprise

The Seagate Exos X18 is an enterprise-class hard drive engineered for high-capacity storage in data centers and cloud infrastructure. It provides 12 TB of storage capacity in a standard 3.5-inch form factor, making it suitable for scalable server and storage systems. The drive connects via a SAS 12Gb/s interface, which supports the high-throughput requirements of enterprise applications. Its design prioritizes operational consistency and long-term durability in demanding environments.

Performance is facilitated by a 7200 RPM spindle speed and a 256 MB cache, enabling sustained data transfer rates up to 258 MB/s. This model is rated for a 550 TB per year workload and a Mean Time Between Failures (MTBF) of 2.5 million hours, supporting continuous 24/7 operation. Integrated rotational vibration sensors maintain consistent performance in dense multi-drive enclosures. The drive also includes features such as end-to-end data protection and hot-swap capability for system integrity and serviceability.
