About this app

Use the best SD speed test tool! Test the speed of internal or external storage, sd card!

Highlighted features:
✔ Measure the speed of your external (removable) SD card
✔ Measure the speed of your internal storage or any disks
✔ Read/write tests using several different combinations.
✔ Show storage type: eMMC, UFS 2.0 and 2.1 or higher
✔ Show class: Class 2, Class 4, Class 6, Class 10, UHS-I, UHS-II and UHS-III
✔ Supporting several file systems like ext4, exFAT or FAT/FAT32.
✔ Support portable and adoptable storage as well
✔ Show storage details: free space, total space, mount options, device name

Supported memory cards:
* Basically any sd cards: Micro SD, SDHC and SDXC
* built-in memory (card)


Good to know:
✔ If the sd card is formatted as adoptable storage, the app may unable to access it directly. In that case either move the app to the adoptable storage (change the install storage), or format the storage as portable storage.


Note: if you measure slow speed, this is not the fault of the app. This is the reality of your phone.
Common reasons: fake sd card, slow sd card reader/hardware problems of the phone, software problems.

Easy to use even for beginners. Quick tests.

Was able to find options quickly because the application UI is very intuitive. I like it that I can run any of the most important tests necessary to understanding what's going on with the SD card. Unfortunately, the application showed me that I purchased an SD card that is slow. I need to learn how to backup the card and replace it with a faster one. Good job on the application guys (and girls). :).

i used this fine before but now i just newly installed, and it gets stuck at the first dialog asking for permission. and won't proceed. now the verify checkbox doesnt work. that's the most valuable part of this.

Works as described, will give a quick test of memory performance. Free version won't work with internal memory configured SD cards. I also compared it against doing it manually with a stop watch and its spot on. The Read performance, is Read to app or RAM memory which is fast than real world, its read to another storage device, which is written to and slows the actual transfer down. Would recommend to anyone wishing to test new SD cards to prove its performance or new hardware.
