HD Tune is a low level hard drive benchmark that provides read performance data, detailed information about the disk and its health (via S.M.A.R.T.), and also offers and error scan option.
The Barracuda ES.2 continues its dominance in the HD Tune tests. We are most impressed with the Average Transfer Rate test, in which the Barracuda ES.2 tears through the rest of the test drives and beats them all by over 15 MB/s. As expected, none of the 7,200 RPM drives, including the Barracuda ES.2, can touch the Raptor when it comes to Random Access Time.
