MP 1,1-5,1 WD Blue SA510 SATA SSD not seen after reboot

[czs]

Is anyone using the WD Blue SA510 SATA drive as a boot drive? The reason I ask is because on my cMP5,1 + OpenCore, the drive is only seen on a cold start; never seen after a warm reboot. I have tried a plain vanilla OpenCore config.plist and also clearing the PRAM\SMC but nothing has worked thus far. I know some other SSDs, such as the Samsung EVO870, exhibit similar behavior and I'm wondering if OpenCore might be the issue.

Any thoughts?

This is a known problem with SATA III drives on the Mac Pro SATA II ports. As I know the crucial MX 500 does not have the problem. I have a WD Red and a MX 500 here and can test these drives, if you want.
