Seagate Exos X18 3.5" 14TB, 7200 RPM, 256MB, SAS Hard Drive, Enterprise

The Seagate Exos X18 is a high-capacity enterprise hard drive designed for data center and hyperscale cloud environments. With 14 TB of storage in a standard 3.5-inch form factor, it addresses the scalability requirements of large-scale systems. The drive utilizes a SAS 12Gb/s interface, which is suitable for high-performance server and Network Attached Storage (NAS) configurations that require high data throughput. It is certified for 24/7 operation, providing consistent data availability for demanding, always-on workloads.

Performance is facilitated by a 7200 RPM spindle speed and a 256 MB multi-segmented cache, supporting sustained data transfer rates of up to 270 MB/s. An average latency of 4.16 ms contributes to responsive data access for server applications. Integrated rotational vibration (RV) sensors help maintain performance in dense multi-drive enclosures by mitigating vibration interference. The drive also includes end-to-end data protection to ensure data integrity and has a mean time between failures (MTBF) rating of 2.5 million hours.
