### Allowed values for STANDARD storage class

`STANDARD` storage class implies more parity than `REDUCED_REDUNDANCY` class. So, `STANDARD` parity drives should be

- Greater than or equal to 2, if `REDUCED_REDUNDANCY` parity is not set.
- Greater than `REDUCED_REDUNDANCY` parity, if it is set.

## Dependencies { #dependencies }

FastAPI depends on Pydantic and Starlette.

### `standard` Dependencies { #standard-dependencies }

When you install FastAPI with `pip install "fastapi[standard]"` it comes with the `standard` group of optional dependencies:

Used by Pydantic:

          listOf(TLS_1_3, TLS_1_2).flatMap { tlsVersion ->
            listOf(Channel, Standard).flatMap { socketMode ->
              listOf(DISABLED, STANDARD).map { tlsExtensionMode ->
                TlsInstance(provider, protocol, tlsVersion, socketMode, tlsExtensionMode)
              }
            }
          }
        }
      } + Channel + Standard
  }
}

sealed class SocketMode

object Channel : SocketMode() {

In that case, you can simply swap the standard `dataclasses` with `pydantic.dataclasses`, which is a drop-in replacement:

{* ../../docs_src/dataclasses/tutorial003.py hl[1,5,8:11,14:17,23:25,28] *}

1. We still import `field` from standard `dataclasses`.

2. `pydantic.dataclasses` is a drop-in replacement for `dataclasses`.

In diesem Fall können Sie einfach die Standard-`dataclasses` durch `pydantic.dataclasses` ersetzen, was einen direkten Ersatz darstellt:

{* ../../docs_src/dataclasses/tutorial003.py hl[1,5,8:11,14:17,23:25,28] *}

1. Wir importieren `field` weiterhin von Standard-`dataclasses`.

2. `pydantic.dataclasses` ist ein direkter Ersatz für `dataclasses`.
