How to test sd card speed via H2testw

It works in the following way:

  1. Launch the program;

  3. Set Data volume, i.e. how many files can be written to the specified location;
  4. In order to check your sd-card press "Write + Verify" button.

Basically, via H2testw you can test the performance of any device connected to your PC, whether it's a HDD, SSD, usb flash drive or a microsd write speed. The most important thing is that your storage device is correctly recognized by your operating system.
