I don’t think consumer SSDs support RAID, so don’t expect the bundled software to read drives correctly. You may need a 3rd party tool like Hard Drive Sentinel.
Problem with the Ultra II is that the Smart variables are uninterpretable … I have no idea how to calculate Media Wear Out for example without using the SSD Dashboard.
Saying that, supposedly Smartmontools 6.6 will support the Ultra II, so if you wait a couple of months, you can use that as well to monitor the array.
