manage disk write caching for external storage on Windows 10

On Windows 10, disk write caching is a feature that uses the faster system memory to temporarily queue write commands until the storage device is ready to commit them to disk. This approach improves performance since the application doesn't have to wait for the drive to continue operating.

While it's a useful feature, the downside is that a system failure, power outage, or accidental removal can result in data loss or corruption. Also, some third-party applications do not support this feature, causing errors and other problems.

Windows 10 includes 2 different policies to manage storage devices, including "Quick removal" and "Better performance." Quick removal is the default setting for external storage, and it does not store any data in memory, making the storage always ready to be disconnected. This means that you can remove the drive skipping the Safely Remove Hardware option without the risk of losing data, but there's a performance trade-off.

The Better performance option is the default option for internal drives, and it's the option that enables the disk write caching feature to improve the overall performance of the drive. If the option is enabled, the system will queue temporary data in memory, and later the drive will automatically commit it to disk. However, to prevent data loss, you'll need to use the Safely Remove Hardware notification icon before disconnecting the external storage.
