SDFormatter identifies the physical capacity of SD/SDHC/SDXC cards, optimize and conduct the best performance in the right file system. With this function, the memory card will return to its original physical capacity
• When testing the speed, please measure the USB 3.0 and UHS-I compatible card reader on a PC equipped with USB 3.0 interface. In order to achieve high speed UHS-I performance, not only the card side, but also the host (computer, camera, card reader, etc.) must be UHS-I compatible. Therefore, it is necessary to measure the speed of a high-speed SD card and a USB 3.0/UHS compatible card reader. Otherwise, the cards will not be able to generate their original speed
