Backblaze Hard Drive Stats for 2017

Hard Drive Reliability Statistics for Q4 2017

At the end of Q4 2017 Backblaze was monitoring 91,305 hard drives used to store data. For our evaluation we remove from consideration those drives which were used for testing purposes and those drive models for which we did not have at least 45 drives (read why after the chart). This leaves us with 91,243 hard drives. The table below is for the period of Q4 2017.

Take backblaze stats as a guide only. Their HDD is set in a dry, cold atmosphere in their DataCenter under almost perfect settings (clean voltage, minimal surges).

Our home PCs are subject to frequent daily power up/down cycle, sudden trips and may be subjected to poor ventilation.

So reliability may differ.
