I'm using Storage Spaces on Windows 10 with a two-tier setup (SSD & HDD). However, I noticed I wasn't getting the expected performance out of the configuration. I've done some research, and it appears as though something is wrong with the tiering. The volume does 'work', it's just clearly running at HDD speeds.
The setup:
SSD Tier: 2x 512GB SSD
HDD Tier: 4x 4TB HDD + 2x 6TB HDD
Some basic status commands:
PS> Get-StoragePool -IsPrimordial $FALSE
FriendlyName OperationalStatus HealthStatus IsPrimordial IsReadOnly Size AllocatedSize
------------ ----------------- ------------ ------------ ---------- ---- -------------
Data OK Healthy False False 26.34 TB 24.87 TB

However the optimization report is particularly interesting:

So far the only actual error I've been able to find is the following:

Any suggestions on what that error means, or where to go from here would be greatly appreciated
