I want to test the read speed on an Ubuntu Server hard drive like one would do with
hdparm -t, but I need to automatically this on multiple machines where I don't know beforehand what
dev the main HDD is, so I can't just
hdparm -t /dev/sda. I would like to be able to run it on the
home folder or on the hard drive containing it, if there's a way to do that in bash.
