🎲iOS devices added to comparison (iPhone Xs X 7 6s)🎲

â—¤CPDT (Cross Platform Disk Test) is a performance benchmarking app that measures I/O speed of permanent storage (internal storage/NAND/NVMe/UFS/SD card) and system memory (RAM) of your phone. Besides Android this app has Windows and macOS versions which makes it possible to stack you phone up against PCs Macs laptops (and their SSD/HDD). There's a benchmarking database with test results for all sorts of devices which is available though app. You can peek at a performance of a device of interest or compare benchmark results of your own phone against .


â—¤Windows and Mac versions can be found at the link:

â—¤The benchmarking suite includes the following 5 tests:

â—‰ Permanent storage tests
┊
╰┄◎ Sequential write
┊
╰┄◎ Sequential read
┊
╰┄◎ Random write(4KB block)
┊
╰┄◎ Random read (4KB block)

â—‰ RAM test
┊
╰┄◎ Memory copy

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



â—¤Various IO settings are available in Options and let users control:

â—‰ Test File size
┊
╰┄◎ 0.5GB ┄◎ 1GB ┄◎ 2GB ┄◎ 4GB ┄◎ 8GB ┄◎ 16GB

â—‰ Write buffering
┊
╰┄◎ On ┄◎ Off

â—‰ In memory file caching
┊
╰┄◎ On ┄◎ Off


â—¤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 data block position in the test file and measured throughput).
