XR-133 is tested in Certification. Titles that use local storage must not exceed 1 GiB of total writes to persistent local storage or temporary storage in a 5-minute increment of time. Exceeding this budget triggers the Local Storage Write Limitations system toast, which is treated as a certification failure. For implementation details on local storage on XBOX consoles with the GDK, read the Local Storage section of the GDK documentation.

Test cases

133-01 Local Storage Write Limitations

  1. Install the title and, with it running, navigate through all areas, including but not limited to:
    • Create a game save, reboot the console, and load the game save.
    • Play all game modes and unlock / view achievements.
  2. Observe the title to see whether the Local Storage Write Limitations system toast appears.
Pass: The title doesn’t trigger the Local Storage Write Limitations system toast. Fail: The title triggers the Local Storage Write Limitations system toast.

Common causes of failure

  • Verbose telemetry or debug logging written to disk in retail builds.
  • Streaming caches that write frequently for very small deltas.
  • Save-on-every-frame patterns or overly aggressive auto-save.
  • Middleware writing intermediate files without cleanup.
