14TB CMR drive for enterprise storage

The Seagate Exos X18 ST14000NM001J is a 14TB internal hard drive built for enterprise storage workloads. It uses conventional magnetic recording at 7200 RPM with a 256MB cache and a SATA 6.0Gb/s interface. The helium-sealed design supports high-capacity density in a standard 3.5-inch form factor.

Suits high-capacity SATA arrays.

This drive suits data-centre racks and scale-out storage systems that need maximum terabytes per SATA bay. It is not intended for laptop upgrades, external enclosures or systems that only accept 2.5-inch drives. Builders needing a non-enterprise firmware or a lower power profile for always-on desktop use should consider other models.

SATA 6.0Gb/s interface decides host compatibility

The single specification that determines fit is the SATA 6.0Gb/s interface; the host must provide a matching SATA data and power connection. The drive delivers 4.16ms average latency and 7200 RPM throughput over that link. If the system lacks a SATA port or requires a different physical interface, this unit will not install.
