Power BI Pro Storage Quota
Although Power BI has been evolving for almost five years now, basic concepts are sometimes worth revisiting. Recently, I had a discussion regarding the Power BI Pro storage quota on the Power BI MVP list and I want to share the conclusions confirmed by Microsoft.
For workspaces in shared capacity licensed with Power BI Pro (not a workspace in a Premium capacity):
- There is a per-workspace storage limit of 10 GB. So, My Workspace gets 10 GB and so does any org workspace.
- There is also an unofficial cross-workspace aggregate quota of 10 GB * the number of Pro User Licenses intended as a backstop to prevent abuse so that a Pro user doesn’t keep on indefinitely creating workspaces to get new chunks of 10 GB. So, if you have 50 Power BI Pro users, the aggregate cross-workspace storage quota would be 500 GB irrespective if only one or multiple Pro users contribute. You won’t see the cross-workspace quota in the Power BI Service UI and it’s not exposed through service code.
BTW, you should ignore the “Manage data storage in Power BI workspaces” document until it’s been updated (the current timestamp is 12/20/2018). As it stands, this document contains wrong and incomplete information. For example, sharing datasets, reports, dashboards should have no effect on the workspace storage quota for consumers.
