在 Windows 10 版本1809中的外部存储媒体的默认删除策略中更改Change in default removal policy for external storage media in Windows 10, version 1809

Windows 定义了两个主策略, 快速删除更好的性能,可控制系统与外部存储设备(如 USB 拇指驱动器或支持 Thunderbolt 的外部驱动器)交互的方式。Windows defines two main policies, Quick removal and Better performance, that control how the system interacts with external storage devices such as USB thumb drives or Thunderbolt-enabled external drives. 从 Windows 10 版本1809开始,默认策略是 " 快速删除"。Beginning in Windows 10 version 1809, the default policy is Quick removal.

在早期版本的 Windows 中,默认策略的 性能更好In earlier versions of Windows, the default policy was Better performance.

你可以更改每个外部设备的策略设置,如果断开设备,然后再次将其连接到同一计算机端口,则你设置的策略将保持有效。You can change the policy setting for each external device, and the policy that you set remains in effect if you disconnect the device and then connect it again to the same computer port.

你可以使用存储设备策略设置来更改 Windows 管理存储设备的方式,以更好地满足你的需求。You can use the storage device policy setting to change the manner in which Windows manages storage devices to better meet your needs. 策略设置具有以下效果:The policy settings have the following effects:

  • 快速删除:此策略以一种使设备随时可以随时删除的方式管理存储操作。Quick removal: This policy manages storage operations in a manner that keeps the device ready to remove at any time. 您可以删除该设备,而无需使用 "安全删除硬件" 进程。You can remove the device without using the Safely Remove Hardware process. 但是,若要执行此操作,Windows 无法缓存磁盘写入操作。However, to do this, Windows cannot cache disk write operations. 这可能会降低系统性能。This may degrade system performance.

  • 性能更佳:此策略以提高系统性能的方式管理存储操作。Better performance: This policy manages storage operations in a manner that improves system performance. 当此策略生效时,Windows 可以将写入操作缓存到外部设备。When this policy is in effect, Windows can cache write operations to the external device. 但是,必须使用 "安全删除硬件" 过程来删除外部驱动器。However, you must use the Safely Remove Hardware process to remove the external drive. 安全删除硬件进程通过确保所有缓存的操作完成,保护设备上的数据的完整性。The Safely Remove Hardware process protects the integrity of data on the device by making sure that all cached operations finish.

    重要

    如果你使用 更好的性能 策略,则必须使用 "安全删除硬件" 过程来删除该设备。If you use the Better performance policy, you must use the Safely Remove Hardware process to remove the device. 如果未按照安全删除说明删除或断开设备,则可能会丢失数据。If you remove or disconnect the device without following the safe removal instructions, you risk losing data.

    备注

    如果你选择 " 更高性能",我们建议你还选择 "启用设备上的写入缓存"If you select Better performance, we recommend that you also select Enable write caching on the device.
