I'm running an experiment where I benchmark the speed of reading and writing with and without caching. On Linux, using 'conv=fsync' as an operand makes sure that the output file is entirely physically written before 'dd' exits (for more accurate times). MacOS doesn't have this option for 'conv'. Is this something I should be concerned about as I look for accurate benchmarks? If so, what can I do?Thanks for your time.
Using dd on Mac OS: conv=fsync equivalent?
