Disk write caching is a Windows feature that can improve system performance by using RAM to collect write commands sent to data storage devices, and cache them to be written to later.
The use of fast memory for this task allows applications to run quicker, as they software does not have to wait for data-write requests to be written to the disk.

And while this increase system performance, it can also increase the chances of data loss in case of power or system failure. That is because the data from the write-cache buffer may be lost before it is flushed by transferring the data to the disk.
For this reason, you may want to disable disk write caching on devices for data security and quick removal, or enable it if it is turned off for better performance.
You will need to be signed on as an administrator to make the changes.
Open the Power Menu by pressing the key combination of Win + X, and then click or tap on the Device Manager to open it.
Expand open the Disk drives section, and then double-click or tap on the disk that you want to enable or disable write caching on. This window below will open up.
Go to the Policies tab, and make your choice of either the default Quick removal option, or Better performance one. Doing so will open up the Write-caching policy section below for removable devices, along with a warning on how selecting it may result in data loss or corruption.
It is a good idea to not check this option unless the disk or device has a separate power supply like a UPS that will allow it flush its buffer in case of a power failure.
Make your selection, click OK, and then close the window.
