Product information

Description

WD Red Plus hard drives are designed for small- to medium-sized business NAS environments and SOHO customers who need reliable storage for archiving, sharing and RAID array rebuilding. Built and tested for up to 8-bay NAS systems, these 3.5" HDDs provide compatibility and performance for everyday file storage and network-attached storage use.

Advantages

WD Red Plus drives include NASware 3.0 technology to improve compatibility, integration and reliability in NAS systems. They are optimized for continuous 24/7 operation with an MTBF of up to 1 million hours and use 3D Active Balance Plus to reduce vibration and improve long-term performance. For larger environments, WD Red Pro offers higher-capacity and higher-duty options for systems with 9–24 bays.

Key specifications

Form factor: 3.5-inch HDD
Optimized for: Up to 8-bay NAS systems
Technology: NASware 3.0
Balance control: 3D Active Balance Plus
Designed for: 24/7 NAS operation (MTBF up to 1,000,000 hours)
Use cases: Archiving, sharing, RAID array rebuilding, ZFS and other file systems

How to use

Install the WD Red Plus drive into a compatible 3.5" bay in your NAS enclosure according to the NAS manufacturer's instructions. Use NASware 3.0–compatible firmware and follow recommended RAID configuration and rebuild procedures for your NAS operating system. For best results, pair drives of the same model and capacity and perform regular backups in addition to RAID protection.

Recommendations

Choose WD Red Plus drives for small- to medium-sized NAS deployments up to eight bays. For heavier workloads or larger enclosures (9–24 bays), consider WD Red Pro. Ensure compatibility with your NAS vendor and follow the NAS vendor's installation and RAID recommendations.
