For a speed test /dev/zero isn't the best item to use as the hardware compression will show how good it can be. I would test on files that aren't in the OS cache and will have representative level of
I agree, but if the test with /dev/zero ends with 10MB/s then there is definately something wrong in the system. So the speed test is indeed valid as a first shot test of the "drive only". Jesper --
