Constant Disk Activity

[Scuro]

I'll start off that I have already disabled bitlocker_poolpartunlockedetect.
 

"BitLocker_PoolPartUnlockDetect": {
  "Default": true,
  "Override": false
}

However I still get disk activity across all drives every 15-30 seconds or so.
When I run Process monitor I see the drivepool constantly making requests across all drives 

Process monitor shows some results as BUFFER OVERFLOW and INVALID PARAMETER.

Is this disk activity normal?

Yes, it is, and interestingly the disks can still spin down because this is coming out of the cache. Nothing to worry about.
