Clean install, disk usage at 100%

I've seen that article. and I am in fact not running that driver. I followed the steps and it does not appear in the list.

 

Disk 100% busy, System Unusable

• Windows 10 Education Ed, version 1709
• 1 x SSD boot disk
• Storage Space Device of 2 x 2TB disks mirrored

This is a recent change in behaviour, new in the last 1-3 months I would guess. My Storage Space Device frequently goes to 100% busy, rendering my system more or less inoperable. Any process / event that touches the Storage Space Device results in this behaviour.
I don't see anything relevant in the Event Viewer.

I've tried many of the online suggestions such as disabling search and SuperFetch but that has not helped.

Just now I was trying to update a route in Garmin Basecamp. When I initiated the route recalculation, the Storage Space Device went to 100% busy and stayed there for 10 - 15 minutes or so with the route recalculation showing now progress. Then disk activity
suddenly went to zero and the route recalculation completed in what I would consider a "normal" amount of time.

Last week I was trying to copy music files between my NAS and my desktop, but had the same problems.

"System" Service Using 100% disk

Hi,

Thank you for writing to Microsoft Community Forums.

Did you notice any changes on the computer prior to this issue?

What is the make and model of the computer?

One of the possible reasons for this issue is Advanced Host Controller Interface PCI-Express (AHCI PCIe) running with AtorAHCI.sys driver. Please refer to the article:
Task Manager shows 100% disk utilization on Windows 10 devices

I also suggest to try the steps mentioned in the article: Improve system performance in
Windows 10 and let us know the status of the issue.

Hope it helps.
