Customize your business’s storage mix to fit your specific needs with a full portfolio of enterprise-class WD Gold™ HDDs in capacities of 1TB to 22TB1 , with OptiNAND™ technology in 20TB and 22TB. 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.

More Flexibility, More Freedom

WD Gold™ lets you build out your storage your way with a full portfolio of SATA HDDs from 1TB to 22TB1, engineered for heavy application workloads and designed to handle workloads up to 550TB2 per year. 

Enhanced Reliability

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

Vibration Protection

WD Gold™ drives have sophisticated monitoring electronics that help correct linear and rotational vibrations in real time using enhanced vibration protection technology for improved performance in high-vibration environments.

Plays Well with Others

Specifically designed for use in enterprise-grade storage systems and data centers, WD Gold™ HDDs are broadly compatible with major enterprise operating systems.

Scale Your Business

WD Gold™ drives are available in capacities up to 22TB utilizing the OptiNAND™ technology's capacity-enabling feature.

Helps Protect Your Data

The innovative ArmorCache™ feature (22TB only) provides enterprise power loss protection of your data in write-cache enabled (WCE) mode while increasing performance in write-cache disabled (WCD) mode.

1. 1MB = 1 million bytes, 1GB = 1 billion bytes, and 1TB = 1 trillion bytes. Actual user capacity may be less 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. Projected values for model number WD221KRYZ and WD202KRYZ. 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 device temperature 40°C. Derating of MTBF and AFR will occur above these parameters, up to 550TB writes per year and 60°C device temp. MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty.

Overall great purchase, have a few of these now and while they were out of stock on amazon CCL had them in plenty, also for cheaper than on the WD site. Very worth the cost as the quality and warranty is so good, very quiet driv, bit on the hot side but that's to be expected and as long as you cool it adequately then it's no problem at all.
