-  * ### How do I passthrough a disk?
-
-    When running the container inside a virtualized environment, it is possible to passthrough disk devices directly, instead of binding a folder containing an image. As these devices are already backed by an image on the host, this removes an extra layer.
-
-    This allows for easier management and higher performance. To do so, you can add those devices to your compose file:
-
-    ```yaml
-    environment:

-    devices:

-      - /dev/sdb

-
-    Please beware that any existing data on the device will be wiped, as DSM will format its partition table during first use. So do NOT passthrough devices containing valueable data.
