Hello, can You please share any good command or script which does quick hdd benchmark test in linux command line?
I mean so it does as much disk parameters and as much readable friendly output as possible.

Basic details about amounts of data being read/written and transactions (tps) can be obtained by:
iostat 2
iostat -x 2
(good to watch "tps", "%wa" and "%util" value which can indicate transactions per second, system waiting on the HDD, utilization.
There are a few tests on this page. Titles are highlighted in red color.

------

First command (long test because it include internet speed testing):
wget --no-check-certificate freevps.us/downloads/bench.sh -O - -o /dev/null | bash
..no command output available

Second test for HDD speed (read/write) + US/EU internet speed test:
