These highly reliable solutions for demanding storage environments provide up to 2.5M hours MTBF3 , vibration protection technology, and a low power draw thanks to HelioSeal technology (for 12TB and above). Specifically designed for use in enterprise-class data centers and storage systems, WD Gold SATA HDDs deliver the world-class performance you expect from Western Digital hard drives.

Product Details

Beyond Expectations
WD Gold™ hard drives are performance-optimized for heavy application workloads and are designed to handle workloads up to 550TB2 per year. Whether you need 1TB or 20TB1, the wide capacity range of WD Gold™ HDDs solves for the most demanding storage environments.

Enhanced Reliability
With up to 2.5M hours MTBF3, WD Gold™ hard drives deliver enhanced levels of dependability and durability.

Reimagining the HDD
WD Gold™ offers 20TB on a 9 disk CMR drive with reimagined HDDs utilizing the first implementation of OptiNAND™ technology's capacity-enabling features.​

  1. As used for storage capacity, one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment.
  2. Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred X (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations.
  3. MTBF and AFR: Projected values for model number WD201KRYZ. Final MTBF and AFR specifications will be based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions, workload 220TB/year and temperature 40C. Derating of MTBF and AFR will occur above these parameters, up to 550TB writes per year and 60C ambient (65C device temp). MTBF and AFR ratings do not predict an individual drive's reliability and do not constitute a warranty
