    For example, let’s say you want to calculate the MTBF of a hard drive over a year. During that year, the hard drive operated for 8,760 hours and experienced 2 failures. So, the MTBF for this hard drive over the one year is 4,380 hours per failure.
    There are different metrics like MTBF (Mean Time Between Failures), MTTF (Mean Time To Failures), and MTTR (Mean Time To Repair) that are often used together to tell about the lifespan and reliability of a component. Generally, SSDs are more reliable than HDDs and thus have a higher MTBF value. What Is MTBF?
    A higher MTBF value suggests a more reliable component, indicating that the element is less likely to fail within the specified timeframe. It’s important to note that MTBF is an estimate based on statistical data and models, and it doesn’t guarantee that a specific component will last exactly as long as its MTBF value suggests.
    Count the number of failures that occurred during the same period. Use the abovementioned formula to calculate MTBF by dividing the total operating time by the number of failures. For example, let’s say you want to calculate the MTBF of a hard drive over a year. During that year, the hard drive operated for 8,760 hours and experienced 2 failures.
