What is a good utility to test my external drive through-puts?

I downloaded Blackmagic but it is out in the Video editing weeds. I would like a disk speed utility that provides a simplified through-put result. I am curious about my port speeds on my 2020 27" with my various external drives.

I have not used NovaBench but it does test disk read/write speeds and it is free.
