Get-FileStorageTier says my drive isn`t tiered

[rufus20145]

Hello.

I created Storage spaces drive using your script with two 1 TB SSDs and two 16 TB HDDs. After this Get-StorageTier says that I have two tiers with mirroring, as expected.

But judging by the performance, it seems that all my files written after 1 TB of data are stored on the HDD and are not planning to be moved to the SSD. I access them a lot, but monitoring in HWINFO says, that only HDDs are being accessed.

Also Get-FileStorageTier -VolumeDriveLetter S says, that

The specified volume does not support storage tiers.

and Storage Tiers Optimization task ends with error

Operation requested not supported by hardware (0x8900002A)

I`m using Windows 10 with latest updates, Ryzen 5900X with X570S motherboard.
Do you have any suggestions why could it happen? I`ve moved only 5 TB of 11, don`t want to redo all this again later.
