Performance Test only tests one drive

You can select the drive to test from the Edit / Preferences window.

I just ran Performance test, but it only found one of my drives. I'm trying to use the software to compare the performance of two drives because I'm concerned one has some sort of issue. (Diagnosis software didn't find any problems, but was very very slow to run.)

Can PT do this?
