Overview

Optimal compatibility for NAS systems

Because WD Network drives are specifically engineered for NAS systems with up to 5 drive bays, it's easy to seamlessly integrate these drives into your NAS system. They are designed and extensively tested for compatibility in the unique 24x7 operating environment and demanding system requirements of home and small business NAS.

Exclusive NASWare™ technology

The secret is in the technology. Advanced firmware technology built into every WD Network hard drive, enables seamless integration, robust data protection and optimal performance for systems operating in NAS and RAID environments.

Energy efficient

Innovative technology reduces power consumption and lowers the operating temperature, resulting in a more reliable and affordable solution for always on 24x7 NAS environments.

Enhanced reliability

Your NAS system is always on. A highly reliable drive is essential. With a 35% MTBF improvement over standard desktop drives, the WD Network drives are designed and manufactured to be a more reliable and robust solution for your NAS system.

3D Active Balance Plus

Our enhanced dual-plane balance control technology significantly improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multi-drive system, reduce the hard drive life span, and degrade the performance over time.

3-year limited warranty

The WD Network drive is backed by a 3-year limited warranty for greater peace of mind.

Seamlessly migrate your current system to your new WD drive using Acronis True Image WD Edition, available as a free download on the WD Support site. This software enables you to copy all your data to a new drive so you don't have to reinstall your operating system to get all the benefits of a new drive.
