Overview

An 18TB helium-filled hard drive designed for 24-bay NAS and RAID systems. It runs at 7200 RPM with a 512MB cache and includes NASware 3.0 firmware for continuous operation.

Design and Build

The drive uses a helium-filled chassis to achieve 18TB in a standard 3.5-inch size. It weighs 660g and is engineered for 24x7 operation in multi-bay enclosures. Every unit undergoes extended thermal burn-in testing before shipping.

Performance and Use

Spindle speed is 7200 RPM with a 512MB cache buffer. The drive handles high-intensity workloads in RAID and ZFS environments. NASware 3.0 firmware manages error recovery to prevent drive fallout during array rebuilds.

Key Features

3D Active Balance Plus controls dual-plane balance to limit vibration and noise in dense configurations. A multi-axis shock sensor detects subtle impacts and adjusts head fly height instantly. Error recovery controls are tuned specifically for RAID applications.

Power and Specifications

Idle power draw is 3.6W and operating power is 6.1W. Operational shock resistance is rated at 30G. The drive connects via SATA 6Gb/s interface and carries a three-year manufacturer warranty.
