VM Disk Performance Question

**Moving this to the right board

Not having issues but I'm not the best at judging VM disk performance.  I set up my VM XML for Windows 10 based on a lot of help I found online to use threads and setting my iothreads and emulator to CPUs outside the vCPUs.  I've got the raw disk image for C on my dual Samsung 960 Pro cache and then a D drive which is just an unassigned pass through 1 TB SATA Samsung 860 EVO.  Could someone tell me if my config looks good and the speeds I'm getting from CystalDiskMark look normal?
