# XR-133 Local Storage Write Limitations

> XR-133 limits titles to 1 GiB of writes to persistent or temporary local storage per five-minute window; exceeding it fires the Local Storage system toast.

**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](https://learn.microsoft.com/en-us/gaming/gdk/_content/gc/system/overviews/features/local-storage) 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.
