Does The Transmission Delay Of The Push-type Terminal Block Connector Of The Drone Aerial Photography Sd Card Holder Be High?

The SD card holder push wire terminal block used in drone aerial photography itself usually does not directly cause obvious transmission delay. The main function of this type of push in terminal block wire connector is to provide a stable physical connection and data transmission channel, and its delay mainly depends on the following technical factors:

1. Interface standard influence: The current mainstream SD card adopts UHS-I or UHS-II standards. The theoretical transmission speed of UHS-I can reach 104MB/s, while UHS-II is increased to 312MB/s. push in wire terminal block As long as it meets the corresponding standards, the delay difference can be ignored.

2. Actual sources of delay:
- Card holder quality: Poor quality push fit terminal block connector may cause poor contact and trigger retransmission
- Protocol overhead: The SD protocol itself has a command processing delay of about 1-2ms
- Controller performance: The processing power of the main control chip has a greater impact

3. Comparison data:
Read delay is usually in the order of 0.1-1ms
Write delay is about 1-5ms (more affected by flash memory characteristics)

4. Optimization suggestions:
- Choose a high-quality card holder with a spring locking mechanism
- Clean the gold finger contacts regularly
- Avoid frequent plugging and unplugging during flight
- Use with high-speed SD cards

In general, the delay of the SD card holder push connector block used in professional-grade aerial photography equipment can be controlled at the millisecond level, which has almost no perceptible impact on applications such as 4K video recording. The real transmission bottleneck often lies in the read and write speed of the SD card itself and the efficiency of the file system.、
