+#### Storage kind tags
+
+You can attach the `dagster/storage_kind` tag to an asset to specify the storage technology used to store the asset. For example, `s3` or `snowflake`.
+
+```python file=/concepts/metadata-tags/tags.py startafter=start_asset_storage_kind_tag endbefore=end_asset_storage_kind_tag
+@asset(tags={"dagster/storage_kind": "snowflake"})
+def users(): ...
+```
+
+These tags will appear in the asset graph and can be used to filter assets in the Dagster UI:
