GUI vs command line
Nearly all commands are available in the DiskTester application and are “one click” operations designed to provide useful results with no fuss. For precise control over each command, the command line can be used.
DiskTester does not draw graphs— output is in text form.
However, various spreadsheets are supplied into which you can paste results for an instant graph for commands for which graphing is appropriate, such as fill-volume, run-area-test, run-sequential-suite.
