• Quality and reliability with up to 2.5M hours MTBF(3) to help you store your data with confidence. | (3) MTBF and AFR: 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.
• Specifically designed for use in enterprise-class storage systems and data centers.
