About Disk Speed / Performance Test
Test your disk or sd card speed & performance with this simple but powerful tool. You can test your storage at various locations (auto-detected or manually entered) using default or customized data's size.
With this performance-testing tool you can benchmark any of your phone's storage locations.
App auto-detects following locations:
★ Internal Storage: Device's internal storage. By default, files saved there are application's private files.
★ External Storage: On various devices it may be part of internal storage or external storage (for example SD card).
★ (Optional - varies with device) Secondary Storage: One or more usually removable external storage that are addition to primary external storage (SD card, USB, etc).
App may also perform test on custom location:
Test with custom path and data's size may be performed.
Path may be entered manually or selected by browsing to it.
Data's size is changed by moving the slider.
Please note:
-> benchmarked location should be writable (on some devices you may need extended permissions to access tested locations).
Features:
★ Simple but powerful tool for Disk speed test.
★ Checks bench performance of different internal / external disks (SD Card) or devices (USB).
★ Configurable benchmark methods.
★ Easy to use.
★ Location's free space statistics.
Useful Information:
If data's size is too small system may read from cache (in RAM which is a lot faster than permanent storage) instead of disk what makes results unreliable.
Default benchmarks try to use 2x of RAM size to perform quick and reliable enough tests.
It's recommended to use data's size 5x or more of RAM size for better results.
It's recommended to use less than 80% of available free space at tested location - default benchmarks do.
App tries to read total RAM of device at launch.
If you want to benchmark your external SD card it is usually available as External Storage or one of Secondary Storages.
For maximum performance disk shouldn't do any background operations while benchmarking.
Secondary Storage option only lists currently writable disks / devices, if your device supports USB storages then it won't show them until they are connected.
How to:
Just run app and tap one of default tests and wait for result.
If you want to use custom path or different data's size tap the "Custom Location".
More information is available after tapping "?" button.

Does not recognize my internal storage. Instead it says it has the same size as the external sd card.

Doesn't measure latency, only throughput. Fills entire disk, triggering disk clean up and skewing results.

Good idea, but the test file is way too large and crashes the test. Needs settings. Also, won't find my 2nd partition (or differentiate between the 1st and 2nd partitions) on my lollipop device. On Jellybean, finds all partitions and tests properly.

just wrong information. its not trustable. the speed test results are fake and exaggerated.

Is there any way that expected results could be included for bench marking? Such as a class 6 SD card should xxx and a class 10SD card should be yyy fast?

7,6 МБ, до 9,9 МБ в ОЗУ. Тестирование встроенной памяти и microSD. Плюсы: выбор расположения тестового файла, произвольный его размер. Минусы: только последовательные чтение и запись, на Samsung Galaxy S5 (SM-G900F, Android 6.0.1) после выдачи приложению всех затребованных разрешений при задании размера файла выдается ошибка и размер остается прежним (неизвестным).

Least I can get correct reading this for my sd card. The other apps couldn't keep effect of caching out. But one problem with this is it does not ask for superuser and so it cannot perform test on my second partition which is ext4. Also there is no listing option for ROM and internal storage separately

Based on the time it took to run the test on my SD Card being g roughly double the same on internal memory I cannot see how write speed is almost the same! 32mb/s vs 36mb/s

But, please, solve the problem with filesystems, which can't hold size of test file, which was calculated by app. FAT32 for example can't hold 10GB test file, which app want to use, so i always got file too large error...

Going to be adding a large SD card and format as internal storage on my phone. Needed to see my actual internal memory read and write speeds so I can pick a SD card that won't bog my phone down. Very useful apo for anyone wanting to do this on the new marshmallow system.

I'm getting a write error (file too large) while trying to test my 32GB sd card. First I thought it was the file system but even after a format from within the Android it self, I still get the same error.
