Reader Question: “A way to make DiskTester iterate test for 50 times or more?”


Leslie C writes:

I was wondering if there is a way to make DiskTester iterate a test for 50 times or more? (Currently it can do 5 times)

For example, in sequential suite, each transfer size is 5 times, but I want it iterate 50 times on each size to have larger samplings .... Possible?

MPG: The GUI interfaces in diglloydTools are basic, for mainstream use, the default being 5 iterations for run-sequential-suite.

The command line is versatile and powerful in its capabilities. In Terminal, here is how to iterate 50 times on volume Scratch:

disktester run-sequential-suite --iterations 50 Scratch

It’s also possible to control the starting and ending transfer sizes for run-sequential-suite using additional parameters, as well as the total test size. For example, here the transfers are from 128K to 128MB over a 2GB test file size:

disktester run-sequential-suite --starting-xfer 128K --ending-xfer 128M --test-size 2G Scratch

The command line (Terminal) is admittedly daunting for most users, but extremely powerful over the range of commands, including scriptable usage. Yet one can approach it in steps, gaining confidence gradually. For example, this command invokes DiskTester with the command run-sequential-suite on volume Scratch, using default parameters:

disktester run-sequential-suite Scratch
