High workload rating Delivering dependable performance to any storage environment, WD Gold™ hard drives are designed with a workload rating up to 550TB per year 1, among the highest of any 3.5-inch hard drive. Enterprise-class storage to rely on With up to 2.5 million hours MTBF, WD Gold hard drives deliver reliability & durability, are built for yearly operation (24x 7x 365) within the most demanding storage environments, & are backed with a 5 year limited warranty. Helio Seal™ Technology Featured in over 15 million Western Digital hard drives shipped 2, Helio Seal™ technology allows for higher capacities & less turbulence on large storage arrays. & now on its 4th generation design, Helio Seal™ technology is field-tested & proven to deliver high capacity, reliability, & power efficiency you can trust. Vibration protection Enhanced RAFF™ technology uses sophisticated electronics to monitor the drive & correct linear & rotational vibrations in real time for enhanced performance versus WD’s desktop drives in high-vibration environments. RAID-specific, time-limited error recovery (TLER) Reduces drive fallout caused by the extended hard drive error-recovery processes common to desktop drives. Dynamic fly height technology Each read-write head’s fly height is adjusted in real time to ensure consistent performance for reduced errors & optimized reliability. Dual-stage actuator technology WD Gold 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 testing All WD Gold hard drives are extensively tested across a variety of popular OEM storage systems, SATA controllers, & host bus adapters to ensure ease of integration for a plug & play solution. 7200RPM-Class This 7200RPM-class hard drive delivers the fastest performance with the highest workload rating of any HDD in WD’s line-up. Ensure you have the most capable hard drive regardless of the application with WD Gold.
