, better than most other SD card performance, is a good choice. If you are having problems with your SD card, determine whether to follow some of the following steps: 1. Make sure you are using a genuine SD card. There are some cheap cards that are smaller than the advertised capacity and can not be used for long.2. Ensure the use of the quality of the good power. You can measure your voltage between TP1 and TP2, and if you fall to 4.75v, just do some heavy lifting and it will become very unstab
