Tools to measure Hard Drive Transfer Speed?

I’m trying to debug my incredibly slow iMac issues. One thing I want to investigate is what the transfer speeds on the hard drives are. What are your favorite tools for that information?

I use DiskMark, and meant to mention it yesterday.
Do you have a fusion drive?
Is it in an iMac, Mini, ?

Not a fusion drive a standard spinning one. iMac 2013 Details in another thread here. It’s a faster processor with more cores than my Laptop yet it runs WAY slower and crashes.
