Okay this is weird! First off what I got, 12 core Mac Pro Latest . My start up disk is a OWC 256 SSD! With the standard 1 TB apple 7200 disk as well. I have the latest OS on both, but always use my SSD as my start up disk!

About every 3 times I start up my machine it starts up from the Apple 7200 HD without me changing the start up disk!

I have to manually reset the startup disk BACK to the SSD!

When you are inside the OS.

Go to >System Preferences>Startup Disk> and select the SSD, then restart the computer!.
