Extremely Slow Performance - 100% Disk Usage
I'm setting up a brand new Precision 5820 to be used as a 3D CAD/CAM Machine. It is struggling to open up basic programs like chrome, let alone Fusion360. I have downloaded Dell support assistant and updated all drivers and run all performance checks scans.
The PC has two 500GB HDDs installed (don't get me started on why our default build doesn't include an SSD). I believe it has a raid controller, but can't figure out how to see how it is configured.
I am showing 100% usage on Disk 0. Disk 1 shows 0% usage. When I open Disk Management, I'm seeing Disk 0 containing the C drive as an NTFS and status as healthy. Disk 1 is not initialized.
Under the "create a storage pool" settings screen I am showing Disk 1 and unformatted and attached via RAID.
Was this PC shipped with RAID setup and maybe our corporate IT core load of Windows messed up the raid configuration? What steps can I take to troubleshoot this issue?
Thank you!

Hello,
Task manager > Performance > Open Resource Monitor > disk
check what is writing/reading actively
Also : win10 or win11 ?

How to access the RAID controller setup in UEFI configured systems
I'm sure you know RAID also means 2 or more disks show as 1. If disk 1 is not initialized, it doesn't sound like it's being utilized at all. It has to be initialized and formatted in order for PC to use.
"Was this PC shipped with RAID setup and maybe our corporate IT core load of Windows messed up the raid configuration?" From what I've read in this forum, Precision's are normally shipped in RAID mode. As for 2nd part of your question, that I'm not sure. To date, I haven't heard of Windows breaking RAID. One of our other experts might have to chime in though.

It is a Windows 10 PC. When I was checking the disk usage I believe it was "System" that was using maybe 1MB/s? I can't confirm because I accidentally wiped the drives trying to mess with the RAID configuration, haha.
This issue seems to be fixed by creating a RAID0 Volume and reinstalling Windows.
No idea how the computer got to a non-raid configuration with one uninitialized drive, but hopefully its all good now. PC is snappy and running normal.
Thanks for the input!

Glad you got it working!! : ) I almost had a feeling it might take a reload, but wasn't 100% sure and didn't want you to lose any of your stuff.
