hdparm -t [device]

tells me the read speed. Is there a way to show the write speed? When I man hdarm | grep write I get flags -F, -n, -r and -W, all which do not provide the desired result I am looking for.

Then is there a way to show read and write speeds with one command?

hdparm does not have the ability to find the write speed. According to the information under how to test the read and write speeds of a hard disk in linux, you can time a call to dd, or use the tools Bonnie++ and piozone.

Any idea why hdparm did not implement a write test ?

I use f3probe's f3write to report speed on existing filesystem (not device)

gnome-disk-utility also work but it require UI, see example at:

Note numbers are not same.
