Operating Hour

In reality, this does not mean any drive may fail on and around 360,000 hrs of operation. The better interpretation of our example is that out of 1,000 drives tested for one month, two have failed, which is equivalent to having failure of one drive out of 500, each month (1,000 / 2). This is a 0.2% for one month.
