# VZStorageDeviceConfiguration

The common configuration traits for storage device requests.

## Declaration

```swift
class VZStorageDeviceConfiguration
```

## Overview

Overview Don’t create a VZStorageDeviceConfiguration object directly. Instead, instantiate one of its subclasses, such as VZVirtioBlockDeviceConfiguration. Use the attachment property of this class to access the device’s underlying storage.
