Under the current configuration on 14393.479, the USB drive is checked for better performance. I cannot check if Insider install modified the setting since Insider has been removed from the SSD drive that had exhibited the problem behavior. I will tuck your idea away if I install a future Insider build onto the drive. Thanks for the idea.
Later today I'll boot into 14971 on the HDD and see what that build shows. I'll post back the findings.
