ioping: Measure disk sequential speed on `/dev/sdX`.
$ ioping -RL ${-dev-sdX}
try on your machine
The command "ioping -RL ${-dev-sdX}" is used to measure the disk I/O (Input/Output) performance and latency of a specific storage device (usually a hard disk or solid-state drive).
Here's a breakdown of the command:
- "ioping" is the name of the command-line tool that is being executed.
- "-RL" are two options passed to ioping. "-R" stands for "read test," and "-L" stands for "continuous loop mode." Together, these options instruct ioping to continuously perform read tests on the specified storage device.
- "${-dev-sdX}" is a placeholder for the path of the storage device you want to test. The actual path should be replaced with the appropriate value. For example, if you want to test the first hard disk (/dev/sda), you would replace "${-dev-sdX}" with "/dev/sda".
Overall, this command will continuously measure the read performance and latency of the specified storage device. The output will provide information on various statistics such as I/O time, I/O rate, and latency.
