What Does Mean Time to Failure (MTTF) Mean?
Mean time to failure (MTTF) is the length of time a device or other product is expected to last in operation. MTTF is one of many ways to evaluate the reliability of pieces of hardware or other technology.
Techopedia Explains Mean Time to Failure (MTTF)
Mean time to failure is extremely similar to another related term, mean time between failures (MTBF). The difference between these terms is that while MTBF is used for products than that can be repaired and returned to use, MTTF is used for non-repairable products. When MTTF is used as a measure, repair is not an option.
