Is 100% disk usage in windows task manager normal?

Oct 8, 2019
So I'm running a 2016 windows server VM and the disk usage is always on 100% in task manager. Even when there is only 5 things in there using 0.1MB/s each.

I don't know how this is supposed to show up, since our VMs use a shared SSD RAID array. All of the limits for usage in proxmox for the disk are set to unlimited as well.

The VM seems to hang occasionally for about a minute when using VS, I'm just trying to figure out if the 100% disk usage is cause for concern or if it is just expected to show up that way when using shared disks.


What disk bus are the VM disks using, Virtio-SCSI? And did you installed the newest VirtiIO drivers in the VM?
Also, can you please post some more details of the underlying storage setup? Is the RAID a HW RAID or ZFS?
