So the title pretty much describes my problem. While playing some games, for example Rainbow Six Siege, my disc is always at 95-100% and it's causing issues like crashing my game often and freezing. I don't know which component is the problem here. I have 8GB 1600mhz ram, I feel like that should be enough, so I think it may be my GPU. I have a Sapphire Nitro Radeon R9 380 2GB. I think this is the problem and doesn't have enough Vram. Or perhaps it could be my hard drive. I have a Seagate barracuda 1Gb 7200rpm. Rest of specs are CPU= AMD FX-6300. PSU = Coolermaster B6 600 watts. CPU cooler is coolermaster hyper t4. Thanks in advance.
