A lot of users have been asking on the forums lately if there is a tool that can help check the health of SD/microSD cards. In response to this problem, EaseUS gives a detailed explanation in the following content.
SD/microSD cards are small enough to be used in many small devices, and their large storage capacity makes them ideal for image-intensive data storage. Therefore, SD or microSD cards are also very popular.
Many users are concerned about the health status of their SD cards and want to know if there is a tool to check SD card health on Windows, Mac, or Android. Then, the fact is that an SD card is not like SSD. It does not have SMART, which means it does not have self-monitoring analysis and reporting technology. Monitoring SD card health is not a critical function of how SD cards are used in the first place, so no specific interface for health testing is included.
So there is no need to study the health status of the SD/micro SD card. If you want to know the performance of your SD card, you can try to detect its file system, bad sectors, or read speed. The popular speed-measuring tools are as follows:
- H2testw: Windows only
- AI SD Bench: Android
- Blackmagic Disk Speed: MacOS
