Go for Gold with a WD Gold Enterprise Class SATA Hard Drive
Conquer tough workloads with enterprise-class WD Gold HDDs. Available in 1TB to 20TB(1) capacities, these highly reliable solutions for demanding storage environments provide up to 2.5M hours MTBF(3), 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, the WD Gold SATA HDDs deliver the world-class performance you expect from Western Digital hard drives.
Vibration Protection
WD Gold has 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.
Enhanced Reliability
With up to 2.5M hours MTBF(3), WD Gold hard drives deliver enhanced levels of dependability and durability.
Play Well with Others
Broadly compatible with most PC and major enterprise operating systems. Specifically designed for use in enterprise-grade data centers and storage systems.
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
