fio

Flexible I/O tester.

Tool that will spawn a number of threads or processes doing a particular type of I/O action.

Test random reads:

sudo fio --filename={path/to/file} --direct=1 --rw=randread --bs=4k --ioengine=libaio --iodepth=256 --runtime=120 --numjobs=4 --time_based --group_reporting --name={job_name} --eta-newline=1 --readonly

Test sequential reads:

sudo fio --filename={path/to/file} --direct=1 --rw=read --bs=4k --ioengine=libaio --iodepth=256 --runtime=120 --numjobs=4 --time_based --group_reporting --name={job_name} --eta-newline=1 --readonly

Test random read/write:

sudo fio --filename={path/to/file} --size=500GB --direct=1 --rw=randrw --bs=4k --ioengine=libaio --iodepth=256 --runtime=120 --numjobs=4 --time_based --group_reporting --name={job_name} --eta-newline=1
