I am using MacBook M1 Max version. Under Mac, the speed of sd card (sdxc) can reach more than 70MB/s for both reading and writing. However, in the Windows 11 virtual machine, the sd card is recognized as a portable device instead of a disk, and the speed can only reach 6-10MB, which is much slower. What could be the reason? Is there any solution? Here are screenshots of the smart card reader recognized in Windows and the speed test.
