I do not understand why there are failures on Linux, yet not on other
operating systems. If you run iozone on OS-X, does the same errors
happen? How about a storage stress-test on Windows? Why is Linux going
to have to make these devices go very very slow and what will happen to
the users that now can not operate their devices at the advertised
speeds? Who will handle that support issue?
