+   It is possible to pass-through a disk device directly, by adding it to your compose file in this way:

-    - /dev/disk/by-uuid/45678-45678-45678-45678-45678:/disk3
   ```
 
   Make sure to bind the disk via its UUID (obtainable via `lsblk -o name,uuid`) instead of its name (`/dev/sdc`), to prevent ever binding the wrong disk when the drive letters happen to change.
