The power to handle the small- to medium-sized business NAS environments and increased workloads1 for SOHO customers, WD Red Plus is ideal for archiving and sharing, as well as RAID array rebuilding on systems using ZFS and other file systems. Built and tested for up to 8-bay NAS systems, these drives give you flexibility, versatility, and confidence in storing and sharing your precious home and work files.

Features:

• Compatibility: Unlike desktop drives, these drives 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 aren’t 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.
