Product features
Full range of nearline capacities
From entry-level servers to high end enterprise storage systems, WD Gold hard drives offer the capacities required for the most demanding datacenter environments.High workload capability
Delivering both performance and reliability to any datacenter environment, WD Gold hard drives are designed to handle workloads up to 550TB per year which is among the highest workload capability of any 3.5-inch hard drive.High level of reliability
With up to 2.5 million hours MTBF, WD Gold hard drives deliver one of the highest levels of reliability and durability for yearly operation (24x7x365) within the most demanding storage environments.Vibration Protection
Enhanced 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.RAID-specific, time-limited error recovery (TLER)
Reduces drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.Extended thermal burn-in test
Each drive is put through extended burn-in testing with thermal cycling to ensure reliable operation.Dynamic fly height technology
Each read-write head's fly height is adjusted in real time for optimum reliability.Dual actuator technology
A 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. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy.Compatibility testing
All WD Gold 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.Key selling points
- Specifically designed for use in enterprise servers, datacenter servers, and storage systems
- Tested for 24x7x365 reliability at workloads up to 550TB per year
- High level of reliability with up to 2.5 million hours MTBF
- Performance-optimized for heavy application workloads
