Desktop drives vs. WD Red Plus

Make the right choice for your NAS and select a drive that is purpose-built for NAS, with a range of features that help protect your data and maintain optimal performance. When choosing a hard drive for NAS, consider the following:
- Compatibility: Unlike desktop drives, these 3.5-inch hard drives are specifically tested for compatibility with NAS systems for optimal performance.
- Reliability: Always-on NAS or RAID environment is hot and desktop drives are typically not designed and tested in these conditions like WD Red Plus drives.
- Error recovery controllers: WD Red Plus NAS hard drives are specifically designed with RAID error recovery control to help reduce errors in your NAS system.
- Noise and vibration protection: Desktop drives designed for standalone operation typically offer little or no protection against noise and vibration present in a multi-drive system. WD Red Plus drives are designed to thrive in multi-bay NAS system environments.
