Overview

This helium-sealed 3.5-inch hard drive delivers 18TB of storage for enterprise servers and high-capacity NAS systems. It runs at 7200 RPM with a SATA 6Gb/s interface.

Helium Platform Design

The drive uses a hermetically sealed helium design to reduce internal turbulence and drag. This allows seven disks to fit in a standard 3.5-inch height while lowering power consumption to 6.4 watts during operation.

Enterprise Workload Performance

Built for 24/7 operation, the drive supports a high annualized workload rate. The 256MB cache and Hyperscale technology optimize data flow for multi-drive server and storage array environments.

Reliability and Security Features

The Exos X18 includes PowerBalance technology to manage peak power demands across multiple drives. Digital environmental sensors monitor internal conditions, and the platform supports Self-Encrypting Drive options for data security.
