DescriptionAn innovative storage architecture to help many customers meet their need for exponential data growth.Reimagining the HDD for exponential data growthHDDs with OptiNAND technologyTrusted reliability and quality for data at scaleReimagining the HDD for exponential data growthHyperscale cloud, CSPs, enterprises, smart video surveillance partners, NAS suppliers and more need storage solutions to meet the exponential growth in data creation. When it comes to cost-effective storage of data at scale, hard disk drives (HDDs) continue to play a central role. HDDs deliver the capacity, performance and reliability needed to store vast amounts of data today and well into the future. Investments in HDD technology remain critical to supporting worldwide data growth. Western Digital has developed flash-enhanced drives with OptiNAND technology by vertically integrating the NAND flash with the HDDs. Higher areal density means higher capacities to meet storage challenges.HDDs with OptiNAND technologyOptiNAND integrates an iNAND Universal Flash Storage (UFS) Embedded Flash Drive (EFD) with traditional spinning disk media, and incorporates innovative changes to the firmware algorithm and system-on-a-chip (SoC). OptiNAND is not a hybrid technology. The drive works smarter, with enhanced firmware algorithms taking advantage of expanded metadata that has been offloaded to the iNAND, enabling more tracks per inch (TPI) with resulting increased areal density. The Ultrastar DC HC560, with the implementation of OptiNAND technology’s capacity-enabling features, delivers an unbeaten capacity in a nine-disk platform (2.2 TB/platter) with CMR recording format.Trusted reliability and quality for data at scaleTrust Western Digital and the Ultrastar DC HC560 hard drive to deliver the highest capacity and greatest value for your data center.Main SpecificationsProduct DescriptionWD Ultrastar DC HC560 WUH722020BLE6L4 – hard drive – 20 TB – SATA 6Gb/sTypeHard drive – internalCapacity20 TBForm Factor3.5″InterfaceSATA 6Gb/sData Transfer Rate600 MBpsBuffer Size512 MBSpindle Speed7200 rpmFeaturesConventional magnetic recording (CMR), Energy-assisted PMR (ePMR), HelioSeal, OptiNAND technology, Triple State Actuator (TSA)Dimensions (WxDxH)101.6 mm x 147 mm x 26.1 mmWeight690 gExtended SpecificationsGeneralDevice TypeHard drive – internalCapacity20 TBForm Factor3.5″InterfaceSATA 6Gb/sBuffer Size512 MBFeaturesConventional magnetic recording (CMR), Energy-assisted PMR (ePMR), HelioSeal, OptiNAND technology, Triple State Actuator (TSA)Width101.6 mmDepth147 mmHeight26.1 mmWeight690 gPerformanceDrive Transfer Rate600 MBps (external)Internal Data Rate291 MBps (read) / 277 MBps (write)Average Latency4.16 msSpindle Speed7200 rpmReliabilityMTBF2,500,000 hours24×7 OperationYesNon-Recoverable Errors1 per 10^15Load / Unload Cycles600,000Expansion & ConnectivityInterfaces1 x SATA 6 Gb/sCompatible Bay3.5″PowerPower Consumption6.9 watt (active) 5.8 watt (idle)Environmental ParametersMin Operating Temperature5 °CMax Operating Temperature60 °CMin Storage Temperature-40 °CMax Storage Temperature70 °CShock Tolerance (operating)50 g @ 2 ms half-sine waveShock Tolerance (non-operating)250 g @ 2 ms half-sine waveVibration Tolerance (operating)0.7 gRMS @ 5-500 HzVibration Tolerance (non-operating)1.04 gRMS @ 2-200 HzSound Emission32 dB
