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
┊
╰┄◎ Sequential write
┊
╰┄◎ Sequential read
┊
╰┄◎ Random write(4KB block)
┊
╰┄◎ Random read (4KB block)

◉ RAM test
┊
╰┄◎ Memory copy

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

Various settings are available in Options menu and let users control:

◉ Test file size
┊
╰┄◎ 0.5GB ┄◎ 1GB ┄◎ 2GB ┄◎ 4GB ┄◎ 8GB ┄◎ 16GB

◉ Write buffering
┊
╰┄◎ On ┄◎ Off

◉ In-memory file caching
┊
╰┄◎ On ┄◎ Off

For sequential tests the app builds time-series graphs, for random tests - histograms. Test results can be exported to CSV for further analysis (each row containing block position in the test file and throughput measured).

How is CPDT different from other apps? Most popular benchmarks focus on CPU/GPU (such as Geekbench, AnTuTu) and completely ignore storage performance.
Storage and memory benchmarks rarely lets users change any test settings and limited to specifying test file size. Controlling buffering or caching is not possible (e.g Androbnech) or require device reloading (e.g. A1 SD).
Caching is a mechanism which significantly influences test results. If it is ON test results are affected by RAM speeds and it’s not possible to isolate permanent storage performance in such tests. Cold read scenarios (e.g. device boot or first-time application start) ca not be described by cached reads. Same situation is with buffering which affects write tests. Buffering uses RAM for temporary storing data before persisting it to permanent storage.
CPDT deals with both caching and buffering and by default those are OFF which makes it possible to consistently measure and compare permanent storage performance across devices and operating systems.

Why is storage and memory performance important? It directly affects the level of “perceived” performance. UI freezes can be described in many cases by stutters at storage level. E.g. displaying a loaded web page in browser when it requests data from it’s cahce, scrolling pictures in gallery app (imaging scrolling thousands of them), or going down Instagram feed (previously loaded images will be requested from cache stored on disk).

Chromebook users can use this app after enabling Google Play. In order to access SD/Memory Card the app must be granted “Storage permission” in Google Play setting of Chrome OS.
