A Whole Guide for getting it to run on Windows 10, here you can find a nice Guide... (NOT BY ME), https://forums.bit-tech.net/index.p...es-tiering-in-windows-10.336785/#post-4883399 but i've added a guide how to properly exchange/remove a broken disk in a redundant environment and with a rebuilt of the broken disk. And how to mix resilliencies and got it tiered together. Here i will collect small stuff, around this topic.. Force files to be stored always on a specified Tier, not getting moved automatically by the System: Keep in mind to let the system some space left . To experience great speed and not mention that you are running HDD's, KEEP YOUR PERFORMANCE TIER FREE .. I've 220 GB Performance Tier and when i copy 80 GB to it, it went's just through ist with full speed of the SSD Array.. And the automatic optimization works pretty well.. Use it wisely Pretty simple to do: the Commandlets are: Code: Set-FileStorageTier Get-FileStorageTier Clear-FileStorageTier Pin files by specifying "-FilePath" and the "-DesiredStorageTierClass Capacity" (there are other parameters, as well) Code: PS C:\Users\Stephan> Set-FileStorageTier -FilePath X:\20348.1.210507-1500.fe_release_SERVER_EVAL_x64FRE_de-de.iso -DesiredStorageTierClass Capacity Force pinning to be executed immediately: Code: PS C:\Users\Stephan> Optimize-Volume -DriveLetter x -TierOptimize Clear-FileStorageTier simply by FilePath. Use "Get-FileStorageTier" to query your pinned Files and more. Code: PS C:\Users\Stephan> Get-FileStorageTier -VolumeDriveLetter x FilePath FileSize DesiredStorageTierClass FileSizeOnPerformanceTierClass FileSizeOnCapacityTierCl ass -------- -------- ----------------------- ------------------------------ ------------------------ X:\20348.1.210507-1500.fe_release_SERVER_EVAL_x64FRE_de-de.iso 4757782528 Capacity 4757782528 0 X:\VHDX\vpn3.vhdx 3661627392 Performance 3661627392 0 X:\CoronaData\csse_covid_19_daily_reports.sqlite 34824192 Performance 34824192 0 PS C:\Users\Stephan> Get-FileStorageTier -VolumeDriveLetter x -PinnedStorageTierClass Performance -PinnedState Pinned That's it for now, Peace
