A few weeks ago the author released a new version (5.0.2) of this disk test utility. It is now using some new benchmark methodology, so the results are not comparable to version 3.0.x. I am just trying to understand what these new tests exactly are. There doesn't seem to be any explanation there on this so called "Help" page...

Let's say the test is 4K Q32T1. I understand the "4K" part, but what are queues and threads? How do they affect disk read/write speed? Is there a standard number of queues and threads that one should select when performing these tests to make them representative? Would you use different values for testing an SSD vs HDD vs flash memory?
Thanks!
