While we are quite happy with ATTO disk benchmark, there are also other benches around and most gives similar results. An exception is HDtune Pro 4.01. While the file benchmarks gives you around 225MB/s, the hard drive read spead is under 200MB/s which feels quite odd. Tests were done with the Intel test rig.
