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 that operate 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 NAS systems with multiple bays.
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 engineered to meet the demanding requirements of high-intensity NAS environments that operate continuously with many users, protecting the system.
Tested for reliable compatibility. Western Digital collaborates with various NAS system manufacturers to conduct extensive testing and ensure compatibility with most NAS enclosures.
Protected from 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 from 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.
