There is no overseas packaged product or domestic support. * Only the card itself is 1 year, and a JNH original SD adapter for data transfer is attached separately. * If there is an SD adapter, data transfer is very convenient and can also be used as an SD card.;* The maximum reading speed of this product is 120MB / s, which is based on Sandisk's original standard and requires Sandisk's dedicated card reader SDDR-B531. It is the speed realized under the condition when it is connected to the USB3.0 port in combination with SDDR-B531. Please note that the maximum reading speed is 100MB / s except for a dedicated card reader.;Regarding the use of this product 1) Please use an SDXC compatible device. 2) After setting up this product on the equipment used, it must be formatted on the same equipment. 3) Use a file system called exFAT for the microSDXC card. Use in FAT16 and FAT32 formats is not covered by the guarantee. * Correct knowledge is required to use the FAT16 and FAT32 formats. Customers who use the product without accurate information often have problems such as data loss and incorrect capacity recognition.;4) If you suspect that the capacity is insufficient, we strongly recommend using the SD Formatter provided by the SD Association. SDFormatter identifies the physical capacity of the SD / SDHC / SDXC card and is optimized with the appropriate file system for best performance. By using this function, the memory card will be restored to its original physical capacity.;* Measure with a USB3.0 and UHS-I compatible card reader on a PC equipped with a USB3.0 interface during the speed test. In order to demonstrate the high-speed performance of UHS-I, not only the card side but also the host (personal computer, camera, card reader, etc.) must support UHS-I. Therefore, a device equipped with USB3.0 and a card reader compatible with USB3.0 / UHS are required to measure the speed of the high-speed SD card. If you don't, you won't be able to get the full speed of the card.
