2019 Update on Hard Drive Failure Rates: Seeing More Failures

This review looks at the Q1 2019 and lifetime hard drive failure rates of the data drive models currently in operation in our data centers and provides a handful of insights and observations along the way. To that end the chart below uses quarterly data from Seagate and HGST drives while leaving out Toshiba and WDC drives as we don’t have enough drives from those manufacturers over the course of the last three years. The table below shows the lifetime failure rates for the hard drive models we had in service as of March 31, 2019.
