Upgraded gold finger design on one side of memory card; This design resulted in a more reliable and faster data transfer rate than an SD card with gold fingers on one end of the card. Since it is a Huawei proprietary product, it can only be used in Huawei P30-pro and later products for now. The P30-LITE can use SD or Nano memory cards thanks to the flexible card slot design. The price of Nano Memory 128GB is relatively higher than SD memory card 128GB. If the price drops to SD level, I will upgrade to 256GB Nano memory for my Huawei phones.
