Enterprise-class hard drives engineered to deliver high performance and reliability.WD Red Pro drives are engineered to handle high-intensity workloads in 24 x7 multi-user commercial and enterprise NAS environments. WD Red Pro drives deliver the performance, scalability and dependability businesses require to store, share and collaborate on large amounts of data in multibay RAID-optimized NAS systems.Tuned for NAS with NASwareWestern Digital's exclusive NASware technology fine tunes drive parameters to match NAS system workloads which helps increase performance and reliability.Designed for Continuous OperationWD Red Pro hard drives are designed to handle the rigorous demands of high- intensity 24x7 multi-user NAS environments and increase system durability.Tested for Dependable CompatibilityWestern Digital partners with a wide range of NAS system vendors for extensive testing to ensure compatibility with most NAS enclosures.Protected against Excessive VibrationWD Red Pro drives include Rotation Vibration (RV) sensors that anticipate and proactively counteract disturbances caused by increased vibration. By dispersing excess vibration across the drive chassis, turbulence is minimized, performance is maintained and drives are protected.Built to Absorb ShockWD Red Pro hard drives include a multi-axis shock sensor to detect subtle shock events and automatically compensate with dynamic fly height technology to further protect the drives in NAS enclosures.Engineered with Industry-Leading TechnologyWD Red Pro up to 22TB hard drives feature Western Digital's proprietary OptiNAND technology which leverages integrated iNAND embedded flash to perform key housekeeping functions, freeing up more capacity and improving the overall drive performance.
