Power BI Pro storage limit

Hi pitshyapong 

As I understand it the 10gb storage limit is licenced-based. A pro licence has 10gb of storage in the Microsoft Cloud. This can be in "My Workspace" and over multiple Workspaces (App Workspaces).  With multiple licences the storage is aggregated between the licences. If the Power BI tenant  has 10 licences that's 100gb available for App Workspaces between the 10 licences, but "My Workspace" still has an individual limit of 10gb. 

There are no limits on how many App Workspaces a user can create, provided they stay within the total storage available in their tenant.

There is no way to increase the amount of storage, other than purchasing more licences.

PPU does not have more storage, each PPU licence brings 10gb like Pro.

Premium Per Capacity licences have 100tb (terabytes) of storage and unlimited storage in "My Workspace".

See: Manage data storage in your workspaces - Power BI | Microsoft Docs

Having said that, the Data in a dataset is compressed and depending on the cardinality of your data this can be very efficient. See Data reduction techniques for Import modeling - Power BI | Microsoft Docs

My experience is that it is very rare for anyone to use up their data storage allowance.

Hope this helps
