Notice how all the newer and “ultimate” controller series are missing. They have some support, but overall it’s still pretty lacking.

Mine “hangs” for a while but does EVENTUALLY boot. It takes like 3-5 minutes though which is very unusual. It used to boot in a few seconds (nvme ssd boot drive), so at first I was worried maybe the drive was going bad.

Now we just need their software and firmware updates to run in Linux native (or even wine, I’m not that picky). Excellent controllers for the cost.
