Ok, I got the idea.
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 different drives on
the same box, same OS to compare them, that would be fine, but use these
numbers to compare different OS, well I would trust the outcome.
Why, well, some with soft update, some, don't. Some use cache more then
others and Linux as an example love doing that.
Remember on OpenBSD, the default system return to you when the data is
written to disk and as such, that's why you very rarely loose data if
ever between crash (obviously if you ave some) or lets call it the baby
playing with the on/off switch of your servers. (;>
But in Linux for example, the system return to you sooner but the data
is not save to the drive yet and as such you will get different numbers.
Just remember that if you actually want to try to compare the same things.
