We have received many complaints from customers who have used the product without accurate information, such as loss of data and incorrect capacity recognition.4) If there is a suspicion that the capacity is insufficient, we strongly recommend using the SDFormatter provided by the SD Association. SDFormatter will identify the physical capacity of the SD/SDHC/SDXC card and optimize it with the appropriate file system for best performance. Using this function restores the memory card to its original physical capacity.Please measure with a USB3.0 and UHS-I compatible card reader on a PC equipped with a USB3.0 interface when testing the speed. In order to demonstrate the high-speed performance of UHS-I, not only the card but also the host (computer, camera, card reader, etc.) must support UHS-I. Therefore, a device equipped with USB3.0 and a card reader supporting USB3.0/UHS are required to measure the speed of a high-speed SD card. Otherwise, the original speed of the card cannot be fully realized.
