## Summary Add port of the sdbench utility from PX4-Autopilot: https://github.com/PX4/PX4-Autopilot This tool is useful for evaluating and testing peformance of SD cards, block devices or mount points. Used in conjunction with apache/nuttx#10478 . Documentation available in https://github.com/apache/nuttx/pull/11049 Relevant Kconfig options: ``` CONFIG_ALLOW_BSD_COMPONENTS=y CONFIG_TESTING_SD_BENCH=m CONFIG_TESTING_SD_BENCH_PROGNAME="sdstress" CONFIG_TESTING_SD_BENCH_PRIORITY=100 CONFIG_TESTING_SD_BENCH_STACKSIZE=8192 CONFIG_TESTING_SD_BENCH_DEVICE="/mnt" ``` Help prompt: ``` sdbench: [-b] [-r] [-d] [-k] [-s] [-u] [-v] -b Block size per write (1-65536), default 512 -r Number of runs (1-10000), default 5 -d Max duration of a test (ms) (1-60000), default 2000 -k Keep test file when finished, default false -s Call fsync after each block, false calls fsync only at the end of each run, default false -v Verify data and block number, default true ``` Example usage: ``` nsh> sdbench Using block size = 512 bytes, sync = false Testing Sequential Write Speed...
