Currently I have a 1 tb WD hard drive had it for like 2 years and I have 8gb of ram. I currently have like 600 gb left on my hard drive and last time when I had like 400 gb left it made my cs go get huge lag spikes like I normally have 300 fps and it made me drop to like 20 fps and I have good ping too. But than after I reset my hard drive it all went away. That's why I wanted to upgrade my hard drive to a WD red 2tb hdd. to prevent that from happening again cause im getting a 1070 soon and i wanted to get the most performence out of it.I also have an ssd with like 120 gb left. Or I was just planning on forgetting about the hard drive and just reseting my 1 tb drive right now. or just going to buy 8 more gb of ram to make 16. Cause I also had the same ram for like 3 years too.
