SD Card Test Pro v4.2 MOD APK (Full Version)

SD Card Test Pro is a storage testing app that helps measure read and write speeds on internal memory and external SD cards. It is designed to be easy for beginners to use, with quick tests, speed displays, and result reports containing important data. The app also does not display ads.

Storage speed testing

The app provides several combinations of read and write tests to assess storage media performance. Users can select internal memory or a removable SD card as the test location. In addition to measuring speed, the app can verify written data to detect corruption or signs that a card does not match its actual advertised capacity.

Testing does not damage the storage, but the process may use a significant amount of space. To calculate the storage type and class more accurately, the app requires at least 4 GB of read or write data and a minimum test duration of 10 seconds. Results may be less accurate if the amount of data or the duration is below these limits.

Steps to run read and write tests

First, select the type of storage you want to test: internal or external. If the SD card is not detected, the app will display a message stating that the storage cannot be found. Users can still browse for its location manually if the card is available on the device.

• Select the storage location to be checked.
• Run the write test first before performing the read test.
• Monitor the speed using the indicator on the Dashboard tab.
• Open the Visualization tab to view the current and average speeds as a graph.
• Once the process is complete, check the Results page.

The Results page displays the amount of data processed, storage path, test duration, and speed. The results can also be shared with a single button.

Identifying media type and class

SD Card Test Pro can estimate the internal storage type, including types such as eMMC or UFS versions. For SD cards, the app can identify the class based on speed results, such as Class 10, UHS-I U1, or V10. This calculation depends on the performance measured during the test, so the data size and process duration affect the identification results.

Supported file systems include ext4, exFAT, and FAT or FAT32. The app also supports storage used in portable mode and adoptable storage, with several access limitations to consider.

Advanced settings and file system limitations

Through the Settings panel, users can specify the size of the files to be read or written. The number of test files can also be set from 1 to 10, allowing data requirements to be adjusted to the condition of the storage media.

On SD cards with FAT or FAT32, the maximum size of each file is 4 GB. If the test requires more data, use multiple files instead of setting a single file above that limit. Larger files can be used on exFAT, but older devices may not support this file system.

If the card is formatted as adoptable storage, the app may not be able to access it directly. The options are to move the app to the adoptable storage by changing the installation location, or to format the media as portable storage.
