I can't use any of my HDD's to play any game, any game you could consider "big" in any way, will lag and stutter no matter what on any HDD I have, old or new, doesn't matter. The HDD will go to a 100% usage most of the game on any game or with 100% usage spikes, even just by moving the camera a bit. HITMAN is giving me insane issues, the HDD will keep a 100% load even after the loading screen has ended and will keep loading honestly I don't know frack*** what. Not only HITMAN, that's just an example, it's any game that has somewhat big levels, Rise Of The Tomb Raider, Fallout 4, even the ancient Skyrim... I have 2 SSD's on my system and as expected, they are not affected by this at all. But I should not rely only on my SSD's to play games, some are really big and a good HDD comes in handy, always. And I ony expect longer load times, not I/O lag, because that's my problem, I don't know what to do and it's really frustrating for me. I have a an i7 4770, a GTX 1060, 8GB of RAM, 2xSSD and 2xHDD, all games that have somewhat an open world lag on the HDD, without a fail, all of the time. Tried a new HDD, same problem. Old HDD, same problem. What is going on? Is it a driver? If so, which drivers? What can I do? This is driving me crazy, I have tried disabling Windows services, checking for HDD firmware update, etc... It just can't be that any newer game that is somehwat big lags on my HDD. I mean, a console does it with a 5400 rpm HDD. Please, anyone, help me! :,( By the way, all synthetic HDD benchmarks give good results, while gaming is where they completely lose it.
