SD Card Test

This application allows users to measure the speed of their external and internal storage devices, including removable SD cards. It offers a variety of read/write tests using different combinations and can display the storage type and class, such as eMMC, UFS 2.0 and 2.1 or higher, and Class 2, Class 4, Class 6, Class 10, UHS-I, UHS-II, and UHS-III. It also supports various file systems like ext4, exFAT, and FAT/FAT32, as well as portable and adoptable storage.

The app is compatible with a wide range of memory cards, including Micro SD, SDHC, and SDXC, as well as built-in memory cards. It provides users with important storage details such as free space, total space, mount options, and device name.

One important thing to note is that if the SD card is formatted as adoptable storage, the app may not be able to access it directly. In this case, users can either move the app to the adoptable storage or format the storage as portable storage.

It is important to keep in mind that if the app measures a slow speed, it is not the fault of the app itself. This could be due to various reasons such as a fake SD card, a slow SD card reader, hardware problems with the phone, or software issues.

This application is designed to be user-friendly, even for beginners, and offers quick tests to easily measure storage speed. It is also optimized for SEO, making it easy to find and use for all users.
