Western Digital WD Re 4TB Datacenter Capacity Hard Disk Drive - 7200 RPM Class SATA 6Gb/s 64MB Cache 3.5 inch WD4000FYYZ

Brand :WD Series :RE Model :WD4000FYYZ Packaging :Bare Drive Interface :SATA 6.0Gb/s Capacity :4TB RPM :7200 RPM Cache :64MB Average Latency :6Gb/s Features :High capacity nearline driveMultiple capacities to suit even the most demanding datacenter, enterprise server, or cloud storage needs.Designed for high-intensity applicationsDesigned to handle workloads up to 550TB per year - among the highest workload capability of any 3.5-inch hard drive - delivering both performance and reliability to any datacenter environment.StableTrac (excluding FBYZ models)The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations.Vibration ProtectionEnhanced RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time. The result is a significant performance improvement in high vibration environments over desktop drives.Dual actuator technologyA head positioning system with two actuators that improves positional accuracy over the data track(s).The primary actuator provides coarse displacement using conventional electromagnetic actuator principles.Multi-axis shock sensorAutomatically detects the subtlest shock events and compensates to protect the data.RAID-specific, time-limited error recovery (TLER)Reduces drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.Designed for quality and reliabilityWith 2.0 million hours MTBF, these drives ensure one of the highest level reliability ratings for high-capacity enterprise storage needs.Thermal extended burn-in testEach drive is put through extended burn-in testing with thermal cycling to ensure reliable operation.NoTouch ramp load technologyThe recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.Dynamic fly height technologyEach read-write head's fly height is adjusted in real time for optimum reliability. Usage :For Enterprise Storage Form Factor :3.5" Height (maximum) :25.4mm Width (maximum) :101.60mm Length (maximum) :147.00mm
