CPDT (Cross Platform Disk Test) is a performance benchmarking app that measures I/O speed of permanent storage (internal memory/NAND/NVMe/UFS/SD card) and system memory (RAM).

This app has Windows, macOS and Linux v̲e̲r̲s̲i̲o̲n̲s̲ which allow to consistently run tests across devices with different operating systems. They can be download at the web site: https://maxim-saplin.github.io/cpdt_results/?download

In-app results database makes it possible to compare your phone’s performance to other android smartphones (e.g. Samsung Galaxy Note 10, Xiaomi Redmi 7 etc.) and wide variety of different devices on different platforms (iPhones, Macs, Windows PCs, Android TV Players etc.)

The benchmarking suite includes the following 5 tests:

◉ Permanent storage tests

- test results are given as throughput values measured in MB/s (megabytes per second).
