Disk Usage jumps to 100% When Gaming or Running Antivirus?

[Marktehbuilder]

Whenever I run an antivirus scan on Avast or Malwarebytes, the disk usage for my C drive increases big, often reaching 100%. I ran the Heaven benchmark to see if something similar happened, but the disk usage remained low. But I then ran a game (Fallout 4), and saw that disk usage for my D drive, which is the drive I store all my games, jumped up to 100%. Is this normal? I am not familiar with how much usage drives should take, and would really appreciate help. My drives are:

Sandisk 128GB SSD (OS installed)
WD Caviar Blue 1TB

Don't worry its normal.

Don't worry its normal.

I don't have to worry about performance? Say if I'm doing a virus scan, can I do other things if the drive usage is already 100%?

yes you can

So your problem is on the disk with the os?

"Whenever I run an antivirus scan"

A virus scan literally scans your entire hard drive for viruses. You can expect disk usage to hit 100%

Disk usage during games will depend on how much RAM you have available. You didn't mention how much you have in your PC

My setup is

Kingstin Hyper x 8gb memory
Msi 1070 Gaming X
Intel I7 4790k

I think its not going to effect your gaming performance depending which game you play.

It's best to run a system antivirus scan while you're away from your PC doing something else as it's such a resource-intensive process & it needs unhindered access to the drive being scanned, which it won't have if your opening files or running apps on said drive at the same time.

Also disk active time and disk transfer rate are two different things. Disk transfer rate (usage) isn't on a 0-100% scale, since the maximum transfer rate is vastly different for each disk, the graph in most monitoring apps will scale to whatever MB/s or GB/s rating best fits the current processes. Active time should jump to and stay at 100% any time there is a continuous task accessing the disk.

If you really want to see what processes and files are being used and the status of the disk, use Resource Monitor (link at the bottom of the Performance tab of Task Manager) and sort the disk section by Total (B/sec). You'll quickly see which files and processes (images) are using the disk.

I looked at disk section on resource monitor. I I'm only using chrome and at the top of the processes list are System, with about 110,000+ total b/sec and chrome.exe hovering about 8,600 total b/sec. Is that standard? Sometimes when I turn on my computer, everything is slow and I restart it and it works fast again. This is why I'm asking for help.

System is a hard one because there are so many things that use the system handle, like moving and copying files. I wonder what's in CPU and memory usage. Chrome is known for being a memory hog, but it doesn't usually hit disk performance.
