I don't have the AHCI drivers and I'm not sure how to get them. I have tried the regedit options that I have found, but msahci doesn't exist in the registry and another option I found was already at its correct value. I have booted with AHCI in the BIOS, but the device manager doesn't have anything AHCI related and Samsung Magician says it isn't working either. Under storage controllers, Microsoft Storage Spaces Controller is the only thing there. I am running Windows 10.

Is it worth the trouble of getting this to work properly and if so, does anyone know how?

Possible relevant system parts:
i7 6700k
Asrock Z170 Extreme4
850 Pro 500 GB SSD
2 TB HDD

Thanks for looking.

Hi

Is this a fresh windows 10 install or a upgrade from 7 or 8.1?

Does the motherboard driver disk include win 10 drivers?

Most modern motherboards will have hard disk controllers in ahci mode by default
I would expect a fresh install of win 10 to work
If you installed windows with bios or uefi setting in ata compatible mode you will probably need to do a fresh install formatting the c: drive

Were you getting any error messages from windows when booting up?
If driver not loaded you would get a bsod

If you change bios uefi setting for hdd controller you usually get another bsod

The hard drive controller is one of the few which does not auto detect and accept changes under windows

There is a xp program fix hdc designed to rip the hdd controller out of the registry which often works with latter versions of windows
It can be found in Hirens Boot cd

When I got the motherboard and CPU I did a clean install of Windows 7 because I can get it free through my school and then upgraded to 10. I haven't gotten any errors of any kind (with regards to this problem). I have the driver CD that came with the motherboard, but I am not sure if it has Windows 10 drivers or not.

Will there be a noticeable increase in performance if this gets fixed?

Thanks for the quick response.

Here are the results from the benchmark. I'll be honest, I have no idea if these results are good or not.

Start windows 10
Select Safe Mode Boot in msconfig
Reboot go into BIOS
Change Setting to AHCI
Continue into Windows (Safe Mode)
Let Windows do its magic
Uncheck Safe Mode in msconfig
Reboot as normal

This should get you there. I had the same problem but above solved it for me.
