I'm still looking for a decent, "safe" 2-port PCIe SATA controller.
From what I understand, SIL3132 is potentially problematic. I can't tell from recent posts whether the RocketRAID 620 requires a special script or not. Rocket 620, at least, appears to require a script on unRAID 4.7 (which I'm still on), but I'm not sure whether that's required for more recent versions. I'll probably go to unRAID v5 relatively soon (as in, likely before I add drives), but I'm watching a couple of the new issues in the Issue List folder.
