1, Advantages: The appearance size of the nm memory card is as big as that of the Nano-Sim card, only 45% of that of the traditional TF card, or even smaller. You can read 90MB/s and write 70MB/s, and you use eMMC protocol (the main protocol stored in the mobile phone before UFS protocol) instead of SD protocol commonly used in the market, so it is faster and more stable.
2. Disadvantages: the price is higher. The cost performance of products is getting lower and lower.
