WD Red Plus NAS Hard Drive 3.5-Inch
Tackle intensity with a WD Red™ Plus Hard Drive
Packed with 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 the flexibility, versatility, and confidence in storing and sharing your precious home and work files.

• 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 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.
