I recently upgraded my PC and noticed that in many games sudden fps spikes occur. Since it was usually connected to some ingame action (like clicking a button or picking something up) I suspected it is connected to asset loading, and it does look like it is the problem.
When running performance monitor it shows that for the games on the 3TB WD Blue HDD (WDC WD30EZRZ-00Z5HB0) random access time spikes of 200-500 ms happen. If I relocate the game to my other HDD, these spikes (and as expected, the fps spikes too) are gone.
SMART data is fine, I did a full sector check without any reported problems. The drive is not fragmented. Swapping cables and/or ports did not help. Changing energy saving profile to max performance did not help either.
Does anyone have a suggestion what the problem might be?
Thanks in advance
