20TB WD RED PRO NAS HARD DRIVE

Optimized for NAS with NASware™Western 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 22TB, 24TB and 26TB 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. Backed by World-Class Support and WarrantyAs an industry-leading hard drive manufacturer, Western Digital stands behind their NAS storage solutions with the assurance of a 5-year limited warranty and world-class support services for hassle free data storage. Desktop drives vs. WD Red® ProIt is important to choose a drive purpose-built for RAID-optimized NAS systems to ensure optimum performance and preserve your valuable data. Take the following into consideration when choosing a hard drive for your NAS
? Compatibility
Unlike desktop drives, WD Red Pro hard drives are specifically designed and tested for NAS and include NASware™ technology which fine tunes drive parameters to match NAS system workloads for optimum performance. ? Reliability
Desktop drives aren't typically designed for the demands of an always-on NAS environment. WD Red Pro hard drives are designed to perform under tough conditions encountered in high-intensity 24x7 multi-user NAS environments. ? RAID Ready
WD Red hard drives are engineered with RAID error recovery control to help reduce failures within multi-bay NAS systems, unlike most desktop drives that are configured for generic use. ? 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 hard drives include Rotation Vibration (RV) sensors that anticipate and proactively counteract disturbances caused by increased vibration often found in multi-bay NAS systems.Product TypeHard DriveTechnical InformationStorage Capacity20 TBRecording TechnologyConventional Magnetic Recording (CMR)Drive PerformanceSpindle Speed (rpm)7200Buffer512 MBEndurance (TBW)550 TBMean Time Between Failures (MTBF)285.2 YearInterfaces/PortsDrive InterfaceSATAPhysical CharacteristicsDrive TypeInternalForm Factor3.5"Height1"Width4"Length5.8"Weight (Approximate)1.52 lbMiscellaneousDevice SupportedNASWarrantyLimited Warranty5 Year
