Pinning Files to SSD Tier

I was recently troubleshooting an issue with a file transfer performance for Storage Spaces.  The solution was using the Tiered options and we did not want to confused our numbers but wanted to get the max performance counters.  The customer agreed so we used the option below:

>Set-FileStorageTier –FilePath <file> -DesiredStorageStier ($vd1 | Get-StorageTier -MediaType SSD)

What this allowed us to do was "pin" the test file into the SSD Tier.  This worked extremely well and avoided the use of the storage spaces internal mechanisms which would automatically move this file from the tyical HDD into the SSD tier.

Enjoy!
