Product details

Enterprise-class hard drives designed for high performance and reliability in commercial and enterprise NAS environments. WD Red Pro drives are built for high-intensity workloads in commercial and enterprise NAS environments operating continuously with many users. WD Red Pro drives deliver the necessary performance, scalability, and reliability for businesses to store, share, and collaborate on large amounts of data in RAID-optimized multi-bay NAS systems.

Optimized for NAS with NASware. The exclusive Western Digital NASware technology optimizes the drive parameters for NAS system workloads to enhance performance and reliability.

Designed for continuous operation. WD Red Pro drives are tailored to meet the demanding requirements of high-intensity NAS environments operating continuously with many users, ensuring system protection.

Tested for reliable compatibility. Western Digital collaborates with various NAS system manufacturers to conduct extensive testing and ensure compatibility with most NAS enclosures.

Protected against excessive vibrations. WD Red Pro drives feature rotational vibration sensors that anticipate disturbances from increased vibrations and proactively compensate for them. The vibrations are distributed across the drive enclosure to minimize turbulence, maintain performance, and protect the drives.

Protected against shocks. WD Red Pro drives are equipped with a multi-axis shock sensor that detects minor shocks and automatically compensates with dynamic head height adjustment to further protect the drives within the NAS enclosure.

Developed with industry-leading technologies. WD Red Pro drives with 22 TB and 24 TB feature the proprietary Western Digital OptiNAND technology.
