Using devices #23

I tested this amazing tool and it works great.

Please consider putting a warning in your README file that if one chooses a device for any "write" operation, they may render the device useless as it will destroy the content of the raw device. But, that is not the case while defining a file as a target that can reside on an NVMe/SSD mounted file system.

Maybe this is the responsibility of fio. But I think whoever does a test with fio can understand what's happening on the raw device when write to them directly.

Thank you for your feedback. I see your point, but if fio doesn't warn the end-user, why should the benchmark tool? So I agree with Martins3 on this one: I don't think I want to implement this.
