Samsung 850 SSD on z370 stuck in SATA1 (1.5)

   My data SSD is stuck in SATA "One" according to Samsung Magician! ATTO benchmark confirms this. Sloooowwwww....  How do I fix this??

Details:
I put a z370 Taichi mobo with an existing 1TB Samsung 850 EVO used as one of the data disks (not boot) into the core of a Coffee Lake photo editing box. Win10 Pro 64-bit OS. There is a functioning Samsung 960 Pro 512Gig in the first M2 slot doing duty as the boot drive, and obviously no SATA connectors are plugged into the first two connectors on the motherboard as the 960 needs both of those channels. The Samsung 850 data disk was on a Intel HK3770 (Ivy Bridge) mobo before transferring to this new build. I know I had used Samsung Magician in the old machine, and I believe I'd have caught the interface/speed issue if it was the condition on the Ivy Bridge computer. 

At assembly, because this is an SSD I wanted it to be on the Intel controller, not the ASMedia. A little bit of Internet searching shows others with the same issue and mostly a mystery still be be solved. Some point to Intel drivers for the controller. I have examined the Properties in Device Manager and tried "Uninstalling" it to force re-application of a driver. No improvement. The specific driver is cited as a Microsoft 10.0.16299.15. Driver Update in the Properties dialogs confirms that its the expected driver. Going to the Controller in Device Manager the only controller driver that makes sense for this situation is "Microsoft Storage Spaces Controller" and 10.0.16299.98 and has a date of 2006 (!) That can't be right...

I discovered this in Magician because I saw that Windows wanted to run CHKDSK on that drive at a restart. Whoa... I looked at the Windows Event logs and there were recent errors there for that disk, and so I ran CHKDSK on the Samsung 850 from a command line with "/f" statement. There were a few errors corrected. Nothing massive. This disk is a little less than half full. 

I went into the BIOS and looked on the basic screen and "advanced" for some way to tell the SSD to interface at SATA3. Could not find any tool for specifying SATA connections.

Suggestions? Thanks in advance for any ideas.
