Highlighted features:
* Measure the speed of your external (removable) SD card
* Measure the speed of your internal storage
* Verify written dаta: 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).
Requirements: Android 6.0+
