在 Windows 10 版本1809的外部儲存介質的預設移除原則中變更Change in default removal policy for external storage media in Windows 10, version 1809

Windows 定義了兩個主要原則、快速移除更佳的效能,可控制系統與外部儲存裝置(例如 USB 拇指磁碟機或支援 Thunderbolt 的外部磁片磁碟機)互動的方式。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. 從 Windows 10 版本1809開始,預設原則是 [快速移除]。Beginning in Windows 10 version 1809, the default policy is Quick removal.

在舊版 Windows 中,預設原則是較佳的效能In earlier versions of Windows, the default policy was Better performance.

您可以變更每個外部裝置的原則設定,如果您中斷裝置,然後再次將它連線到相同的電腦埠,您設定的原則就會生效。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.

您可以使用 [儲存設備] 原則設定來變更 Windows 管理儲存設備的方式,以更符合您的需求。You can use the storage device policy setting to change the manner in which Windows manages storage devices to better meet your needs. 原則設定具有下列效果:The policy settings have the following effects:

  • [快速移除]:此原則管理儲存作業的方式,讓裝置在任何時候都能隨時移除。Quick removal: This policy manages storage operations in a manner that keeps the device ready to remove at any time. 您可以移除裝置,而不需要使用 [安全移除硬體] 程式。You can remove the device without using the Safely Remove Hardware process. 不過,若要這樣做,Windows 無法緩存磁片寫入作業。However, to do this, Windows cannot cache disk write operations. 這可能會降低系統效能。This may degrade system performance.

  • 效能更佳:此原則以改善系統效能的方式來管理儲存作業。Better performance: This policy manages storage operations in a manner that improves system performance. 當此原則生效時,Windows 可以將寫入操作緩存到外部裝置。When this policy is in effect, Windows can cache write operations to the external device. 不過,您必須使用 [安全移除硬體] 程式來移除外部磁片磁碟機。However, you must use the Safely Remove Hardware process to remove the external drive. 安全移除硬體進程可確保所有快取作業都能完成,以保護裝置上的資料完整性。The Safely Remove Hardware process protects the integrity of data on the device by making sure that all cached operations finish.

    重要

    如果您使用的是較佳的效能原則,您必須使用 [安全移除硬體] 程式來移除裝置。If you use the Better performance policy, you must use the Safely Remove Hardware process to remove the device. 如果您在不遵循安全移除指示的情況下,移除或中斷裝置,可能會造成資料遺失。If you remove or disconnect the device without following the safe removal instructions, you risk losing data.

    注意

    如果您選取 [較高效能],我們建議您也選取 [在裝置上啟用寫入快取]。If you select Better performance, we recommend that you also select Enable write caching on the device.
