In the world of IoT (Internet of Things) projects, SD card flashing is a common task. BalenaEtcher and dd command are two popular tools for this job. While BalenaEtcher is a graphical user interface (GUI) tool, the dd command is a terminal-based command-line utility. In this article, we'll compare the two tools in terms of speed and provide context on when to use each.

BalenaEtcher Performance
During our tests, BalenaEtcher finished the job of flashing a 2GB image to an SD card in approximately 2 minutes.
dd Command: A Terminal-Based SD Card Flashing Utility
The dd command is a versatile command-line utility available on most Unix-based systems, including Linux. It's used for various tasks, including copying and converting files, as well as flashing images to SD cards.
To use the dd command for SD card flashing, follow these steps:
- Open a terminal window.
- Identify the device name of your SD card using the "lsblk" or "fdisk -l" command.
- Use the following command to flash the image:
sudo dd if=path/to/image.img of=/dev/sdX bs=4M status=progress oflag=sync
Replace "path/to/image.img" with the actual path to your image file and "sdX" with the correct device name for your SD card. Be careful when using the dd command, as it can overwrite data if used incorrectly.
dd Command Performance
In our tests, the dd command took approximately 5 minutes to flash the same 2GB image to an SD card.
Comparing BalenaEtcher and dd Command: Which One to Use?
Based on our tests, BalenaEtcher is faster than the dd command when it comes to SD card flashing. However, the dd command offers more flexibility and can be used for various other tasks. If you're looking for a simple and fast way to flash images to SD cards, BalenaEtcher is the way to go. However, if you need more control or are working with other types of files, the dd command might be a better choice.
