What does a target storage mode set to 'PremiumFiles' mean when writing a PowerShell script?

[HamidBee]

I'm learning about PowerBI Rest APIs and I came across the following PowerShell script:

Set-PowerBIDataset -Id 038f9a64-1fcd-42f2-957a-13a63b3d3235 -TargetStorageMode PremiumFiles

What does a target storage mode set to premium mean?.

Thanks in advance.

I just found the answer on another page:

"Premium: Premium file shares are backed by solid-state drives (SSDs) and provide consistent high performance and low latency, within single-digit milliseconds for most IO operations, for IO-intensive workloads. Premium file shares are suitable for a wide variety of workloads like databases, web site hosting, and development environments. Premium file shares can be used with both Server Message Block (SMB) and Network File System (NFS) protocols."

The full script to change the storage mode to premium should look like this:

Set-PowerBIDataset -Id <Dataset ID> -TargetStorageMode PremiumFiles

(Get-PowerBIDataset -Scope Organization -Id <Dataset ID> -Include actualStorage).ActualStorage

It's very useful to do this for really large datasets.
