Actually, it means that the difference in one particular case isn’t very large. cascopy was not developed to test this issue, and is not representative of all usage scenarios. It was used because it is known not to pass the FILE_FLAG_WRITE_THROUGH flag to CreateFile.

For applications which pass the flag, there may still be significant differences. In this case however, at least you are buying some additional security, in exchange for lower performance.
