redundancy or better drive space utilization.

To get an idea of how various combinations of data and parity drives affect the storage usage, let’s take an example of a 100 MiB file stored
on 16 drive MinIO deployment. If you use eight data and eight parity drives, the file space usage will be approximately twice, i.e. 100 MiB

   * a default value.
   *
   * If this does read a value, it starts with the tag and length, and reads an entire value,
   * including any potential composed values.
   *
   * If there's nothing to read and no default value, this will throw an exception.

## 針對表單的 Pydantic 模型 { #pydantic-models-for-forms }

你只需要宣告一個 **Pydantic 模型**，包含你要接收為 **表單欄位** 的欄位，然後將參數宣告為 `Form`：

{* ../../docs_src/request_form_models/tutorial001_an_py310.py hl[9:11,15] *}

**FastAPI** 會從請求中的 **表單資料** 擷取 **各欄位** 的資料，並將這些資料組成你定義的 Pydantic 模型實例。
