Desktop Drives vs. WD Red Plus
Do right by your NAS and choose the drive purpose-built for NAS with an array of features to help preserve your data and maintain optimum performance. Take the following into consideration when choosing a hard drive for your NAS:
- Compatibility: Unlike desktop drives, these 3.5 HDDs are specifically tested for compatibility with NAS systems for optimum performance.
- Reliability: The always-on environment of a NAS or RAID is a hot one, and desktop drives arent typically designed and tested under those conditions like WD Red Plus drives are.
- Error Recovery Controls: WD Red Plus NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system.
- Noise and Vibration Protection: Designed to operate solo, desktop drives typically offer little or no protection from the noise and vibration present in a multi-drive system. WD Red Plus drives are designed to thrive in multi-bay NAS system environments. WD40EFPX
