Definitions

  1. Mean Time To Failure. The average time a non-repairable component or system operates before it fails for the first time.

    In plain English: How long something is expected to work before it breaks for the first time. Mostly used for hardware that gets replaced rather than repaired.

    Example: "The MTTF on those SSDs is rated at 2 million hours, but we still plan for replacement every three years because vendor numbers are optimistic."
