FYI, you may have noticed that I moved your post from the wrong thread here.
I haven't noticed any issues using multiple drives at the same time. But one of my drives on the SATA expansion card isn't used a lot.
To test this, I copied a big movie from my ZFS array to my NVMe drive to remove that as a limiting factor and then simultaneously copied the file to both of the drives connected to the expansion card. The throughput is where I'd expect each to be.
