Enterprise Capacity for Data Centres

The Seagate Exos X18 is an 18TB 3.5-inch internal hard drive built for cloud data centres, hyperscale storage and enterprise NAS systems. It targets operators who need maximum capacity per drive bay in always-on environments. The SATA 6.0Gb/s interface and 256MB cache support heavy read and write workloads across RAID arrays and distributed file systems.

Sustained Workload Behaviour

Rated at 2.5M hours MTBF, the drive is engineered for continuous operation rather than burst transfers. Helium side-sealing weld technology and PowerBalance optimisation keep power draw proportional to capacity during extended duty cycles. The 7200 RPM spindle and 4.1ms average seek time deliver consistent throughput for backup, restore and scale-out applications.

Capacity Decides Fit

The single specification that determines suitability is the 18TB capacity in a standard 3.5-inch form factor. Systems requiring denser storage per slot will match this drive; builds needing less raw space or a smaller physical size will not.
