Got a new SSD but having FPS issues in games now

So I upgraded my SSD from a 64 GB Transcend one to a Samsung EVO 850 250GB (which already took 4.5 hours because of a misunderstanding when looking up on how to clone drives), and now I'm having issues with FPS..

I've tried reinstalling GPU drivers, and tried the solutions mentioned in the links below

Since creating this post I've also tried updating the SATA/AHCI controllers

In the second link there's a mention of a registry entry that I don't have, probably due to running windows 10 and not 7. The drives were also already set to AHCI.

Specs:

* Windows 10 Pro * Intel i5 4690K * EVGA GTX 970 Superclocked ACX 2.0 * MSI Z97-G43 * Samsung EVO 850 250gb * Western Digital Black 1 TB

EDIT: Benchmarks
