What Is The Data Transmission Speed Of The Drone Sd Card Holder Push Wire Terminal Block?

The data transmission speed of the drone SD card holder push wire terminal block mainly depends on the interface standard it adopts. At present, the SD card holders push in terminal block wire connector used by mainstream drones are mostly SDHC or SDXC standards, supporting UHS-I or UHS-II bus interfaces. The theoretical maximum transmission speed of the UHS-I interface is 104MB/s, and in actual use it is usually between 80-95MB/s; while the theoretical speed of the UHS-II interface can reach 312MB/s, and the actual speed is about 250MB/s.
The specific push in wire terminal block transmission speed is also affected by the following factors: 1) the read and write performance level of the SD card push fit terminal block connector itself, such as Class10, U1, U3, etc.; 2) the processing power of the drone main control chip; 3) the quality of the data line and the stability of the connection. Most consumer-grade drones use the UHS-I interface, which can meet the needs of 4K video recording. Professional-grade drones may be equipped with a UHS-II interface for faster material transmission speeds.
Test data shows that under typical usage scenarios, the sustained write speed of the drone SD card holder push connector block is about 45-90MB/s (UHS-I) or 150-200MB/s (UHS-II), and the read speed is usually 10-20% higher than the write speed. This speed is sufficient to support most aerial photography applications, including high-bitrate 4K/60fps video recording.
