WD Gold Datacenter Hard Drives

Scale it in Gold
With up to ten times the workload capacity of desktop drives, WD Gold™ hard drives employ advanced technology to deliver among the best in reliability, capacity, power efficiency and performance. Designed for a multitude of Datacenter-specific applications, WD Gold™ hard drives are perfect for high-availability server and storage arrays that demand the most robust storage device available with 24/7 premium customer support.

Full range of near line 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 3.5inch 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 over our desktop hard drives.

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 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.


Enterprise servers, datacenter environments, enterprise storage systems, data warehousing/mining, enterprise NAS, and high end surveillance systems.

The WD Advantage
WD puts datacenter products through extensive Functional Integrity Testing (F.I.T.) prior to any product launch. This testing ensures our products consistently meet the high quality and reliability standards of the WD brand. Following a FIT test the Enterprise System Group (ESG) testing validates interoperability with HBAs, operating systems, and drivers, to ensure an even greater level of quality, reliability, and peace of mind.

WD also has a detailed Knowledge Base with helpful articles and software utilities. Our customer support lines have long operational hours to ensure you get the help you need when you need it. Our toll-free customer support lines are here to help or you can access our WD Support site for additional details.


This drive is compatible with any server that accepts 3.5inx1.0in SATA Drive.
