The Seagate Exos X18 is a high-capacity internal hard drive designed for enterprise-level storage applications. It provides 18 TB of storage within a standard 3.5-inch form factor, making it suitable for bulk data requirements in data centers, cloud infrastructure, and large-scale storage systems. Its SATA 6 Gb/s interface allows for integration into a wide range of server and NAS hardware configurations. The drive is constructed to handle the consistent, heavy workloads associated with professional data environments.
Performance is managed by a 7200 RPM spindle speed and a 256 MB cache, which facilitate sustained data transfer rates of up to 270 MB/s and an average latency of 4.16 ms. This model is engineered for continuous 24/7 operation and has a mean time between failures (MTBF) rating of 2.5 million hours. Integrated rotational vibration sensors help maintain performance consistency in dense, multi-drive arrays, while S.M.A.R.T. monitoring and end-to-end data protection support data integrity during operation.
