Windows10 Professional editions21H2，About the Hard Disk write in Cache Policy and Other Problems

Question

Windows10 Professional editions21H2
1、Only check Enable Write Cache on the device. What conditions need to be triggered to enable the data in the cache to be written to the device (hard disk)?
2、Only check Enable Write Cache on the device. When will the cached data be written to the device (hard disk)?
3、Only check Enable Write Cache on the device. Can I modify the delay time of writing to the device (hard disk)?
4、In the deletion strategy, can you select a better performance and then uncheck Enable Write Cache on the device? What impact will this have?
5、Select better performance in the deletion policy, and then uncheck Enable write caching on the device. Is the data writing strategy consistent with the quick deletion strategy, and is it directly written to the device (hard disk)?
6、In the deletion policy, select better performance, and uncheck Enable Write Cache on the device. In this way, compared with fast deletion, except for the different steps of security hardware deletion, are the write policies and other operation policies consistent?
7、After the data is successfully written into the mechanical hard disk, the computer will be shut down immediately. For the sake of data security, would like to choose quick deletion or better performance in the deletion strategy? If better performance is selected, do you want to enable write caching on the device in the write caching policy?
thank you!
