Hello list.
Can anyone suggest me a way to measure a hard disk speed?
I'm thinking about a tool like linux's hdparm / sdparm
A simple solution could be measuring the time required for the generation of a
big file, something like time dd if=/dev/zero of=/some/file bs=whatever
count=whatever

Write a random number on a piece of paper. I'd suggest 42 for
laughs. At least people will understand how you derived it.
From a book?
Better: from THE book? :-)
You can't just define something as complicated as hard disk speed
in one number. Or twenty numbers.
Ok, I got the idea.
time
You can use iostat(8) if you're trying to ascertain the transfer rate the of
drive... are you?
$ iostat -d
wd0 cd0 cd1 fd0

time + dd will do.
Just remember, that would be kind of fine for the same OS, but not that
reliable between different OS. As long as you try
