SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information & diagnostic utility. Sandra provides most of the information (including undocumented) you need to know about your hardware, software and other devices whether hardware or software. In order to test the hard drive, SiSoftware Sandra 2010c was used as part of the test suite. The graphical results that Sandra gives you after the test is completed nicely shows how drives perform over time and where on the drive the performance is seen.
