Strumento open-source open-source che misura la velocità di archiviazione permanente / scheda SD e RAM 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). 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
