3D Active Balance Plus

Improved dual-plane balancing technology significantly improves overall drive performance and reliability. Incorrectly balanced hard drives can cause excessive vibration and noise in a multi-drive system. This results in deterioration of drive performance and reduced drive life.

Continuous duty environment

NAS systems operate continuously, so a reliable hard drive is of paramount importance. With an MTBF of up to 1 million hours, the WD Red Plus drive excels in continuous operation environments.

Traditional desktop drive and WD Red Plus drive comparison

Give your NAS a chance and choose a hard drive specifically designed for it with features to help secure your data and ensure optimal performance. When choosing a hard drive for your NAS system, consider the following:

• Compatibility: Unlike traditional drives, these drives have been tested for compatibility with NAS systems and optimal performance.
• Reliability: A constantly active NAS or RAID environment is subject to high temperatures, and desktop drives, unlike the WD Red Plus, are not typically designed and tested for these conditions.
• Error recovery systems: WD Red Plus NAS hard drives are equipped with a RAID error recovery system to help minimise failures in the NAS system.
• Protection from noise and vibration: Designed for standalone operation, desktop drives do not offer sufficient protection against vibration and noise that occurs in multi-drive systems. WD Red Plus drives are specifically designed for multi-bay NAS systems
