What games are you having the issue most noticeable in?

Could be a faulty SATA cable that is messing with the Read/Write speeds on the HDD? Or maybe a faulty HDD itself, but I wouldn't think so.

Is the 2tb drive 7200rpm?

Download and use MSI Afterburner when playing. It will show everything thats being used. Like cpu usage, core temps, fps ets.
When fps goes down, see if anything goes down at the same time.
