Comments on SD Card Test for Android

★★★★★ Michael Elkin · May 3, 2025

Can test external storage I wanted to test the speed off an external ssd and this was the only ones I found that could do it. You first have to find the drive and select that folder and grant usb storage permission. The only app I found that could do it.

Good app and can customize the test file size but verify card if fake is behind pr over.

Do not use if you do not know how and what this tech is🤔 data will be corrupted if you did the wrong way

★☆☆☆☆ Marius Cosmin · Nov 29, 2025

Doesn't find external Micros card, and also they sell your data to hundreds of Vendors including scanning your IP and installing cookies on your phone.

★☆☆☆☆ Justin Durham · Jan 7, 2026

*DANGER APP PLAYS UNSKIPPABLE AD DURING TEST, FORCE CLOSING CAN CORRUPT DATA. Detailed interface. All the info one could need. I have one of the little micros to usb c adapters. It detected my card and displayed all available info. The write-test was a success. HOWEVER. The app launched an AD DURING the read-test. Understandable that a free app would have ads. The ad ruined the first read-test. So I tried the test again. Only for the app to launch another ad!
