SD Card Test Pro v2.0

SD Card Test Pro is an app for Android devices that allows users to test the performance and speed of their SD cards. The app is designed to help users determine whether their SD card is working properly and whether it is capable of meeting their storage and performance needs.

Features of SD Card Test Pro

• Measure the speed of your external (removable) SD card
• Measure the speed of your internal storage
• Verify written data: damaged or fake card detection
• Read/write tests using several different combinations.
• Customized benchmarks
• Detecting storage type and class
• Supporting several file systems like ext4, exFAT or FAT/FAT32.
• Support portable and adoptable storage as well

How to use it

• First select the storage type you want to test it. You can choose between internal or external storage.
• If the app could not detect any SD card, then it will display a "Storage cannot be detected" message, but you are still able to browse it manually (if there is sd card in your device).
• After you selected the storage type, choose between write and read test, but firstly always run a write test.
• On the first tab (Dashboard), you can see the speed on the speedometer while on the Visualization tab, you can check the current and average speed on the graph.
• After the test is finished, on the Results tab you can check the details like processed data, storage path, runtime or speed.
• Furthermore, here the app will detect the type of your internal storage (like eMMC or UFS version) and will detect the class for the SD card (like Class 10, UHS-I U1, V10).
• Important thing that the app will do these calculation based on the speed, thus it needs at least 4 GB of read or written data and at least 10 seconds of run time, otherwise the result can be misleading.
• Finally, you can share the results easily with one-button method.

For professional people

• In the Settings panel, you can adjust the size of the file(s) to read/write, you can change the number of the files (between 1-10).
