Western 0B36404-20PK Ultrastar Sata Series 0b36404 8tb 7200rpm Sata3sata 6.0 Gbs 256mb Hard Drive (3.5 Inch)

General InformationUltrastar hard drives feature up to 10 times the workload rating of desktop drives and employ advanced technologies for enterprise-class reliability, power efficiency and performance. Designed from the ground up to be an ultra-robust storage device, Ultrastar drives are the perfect solution for your business.High Workload RatingDelivering dependable performance to any storage environment, Ultrastar hard drives are designed with a workload rating up to 550TB per year, among the highest of any 3.5-inch hard drive.Enterprise-class Storage to Rely OnUltrastar is our top-end drive for data centers. With up to 2.5 million hours MTBF, Ultrastar hard drives deliver reliability and durability, are built for yearly operation (24x7x365) within the most demanding storage environments, and are backed with a 5-year limited warranty.HelioSeal TechnologyFeatured in over 30 million Western Digital hard drives shipped, HelioSeal technology allows for higher capacities and lower power on large storage arrays. And now on its 5th generation design, HelioSeal technology is field-tested and proven to deliver high capacity, reliability, and power efficiency you can trust. HelioSeal is a key technology on 10TB capacities and above. Vibration ProtectionEnhanced Rotational Vibration Safeguard (RVS) technology uses sophisticated electronics to monitor the drive and correct linear and rotational vibrations in real time for improved performance versus traditional desktop drives in high-vibration environments.Dynamic Fly-height TechnologyEach read-write head's fly height is adjusted in real time to ensure consistent performance for reduced errors and optimized reliability.Dual-stage Actuator TechnologyUltrastar drives feature a dual-stage actuator head positioning system for a high degree of accuracy. The primary stage provides course displacement while the secondary stage uses piezoelectric motion to fine tune the head positioning to a higher degree of precision. Compatibility testingAll Ultrastar hard drives are extensively tested across a variety of popular OEM storage systems, SATA controllers, and host bus adapters to ensure ease of integration for a plug and play solution.Technical InformationStorage Capacity: 8 TBDisk Format: 512eDrive PerformanceSpindle Speed (rpm): 7200Buffer: 128 MBNetwork & CommunicationWireless LAN: NoInterfaces/PortsDrive Interface: SATADrive Interface Standard: SATA/600Power DescriptionOperating Power Consumption: 8.80 WPhysical CharacteristicsDrive Type: InternalForm Factor: 3.5"Height: 1"Width: 4"Depth: 5.8"Weight (Approximate): 1.43 lbMiscellaneousEnvironmentally Friendly: YesEnvironmental Certification: RoHSDevice Supported: ServerDevice Supported: Storage SystemWarrantyLimited Warranty: 5 Year
