How to build a calculator that can predict drive life expectancy? First, you would need to gather the following information about the drive:  MTBF,  Load/Unload cycle specification, WRL,  POH. With this information, you can use the following formula to estimate the drive life expectancy: Drive Life Expectancy = (MTBF / (24 * 365)) * (1 … Continue reading HDD life expectancy calculator
