Can't test internal iMac Fusion drive with Blackmagic Disk Speed Test?

I was checking the read/write speeds of the external drives I use with FCP X and lastly decided to test my iMac's fusion drive.


This is the option I get to select it but when I do it says it can't be done because the drive is "Read Only".



There is no other location on the internal drive for me to select?



I get the same result with my 2012 Mac mini.

I assumed that literally when it asked me to select a drive, I had to select the drive itself and not something on that drive.

I too faced the same perplexity the first time I tried to test my internal drive.
