WD Red™ Pro for large enterprises
For business customers seeking a NAS system for intensive applications, WD Red™ Pro hard drives offer exceptional performance for medium and large businesses with extreme demands.

3D Active Balance Plus
Our advanced dual-plane mass balancing technology significantly improves the overall performance and reliability of the drive. Hard drives without proper mass balancing can cause excessive vibration and noise in a multi-drive system, reducing drive lifespan and leading to performance degradation over time.

A continuously operating environment
Your NAS system runs 24/7. Therefore, extremely reliable storage is essential. With an MTBF of over 1 million hours, the WD Red™ Plus is designed for continuous operation.

Desktop hard drives compared to WD Red™ Plus
Choose the right NAS-optimized hard drive with a wide range of features to protect your data and maintain peak performance. Consider the following when selecting a hard drive for your NAS system:

- Compatibility: Unlike desktop drives, these hard drives are tested for compatibility with NAS systems to ensure optimal performance.
- Reliability: Continuous operation of a NAS or RAID is extremely demanding. Desktop hard drives are generally not designed and tested for these conditions – unlike the WD Red™ Plus.
- Error recovery logs: WD Red™ Plus NAS hard drives are specifically designed with RAID error recovery logs to help reduce failures in the NAS system.
- Noise and vibration protection: Desktop drives are designed for single-drive operation and therefore typically offer little to no protection against the noise and vibration found in multi-drive systems. WD Red™ Plus hard drives are optimized for use in multi-bay NAS environments.
