SD卡检测大师 V2.2

Use the best SD card test tool! Test the speed of internal or external storage! No ads! Easy to use even for beginners. Quick tests.

Highlighted features • 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

The tests are not destructive, but can consume a lot of space temporary during the measurement.

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).
