I am addressing several points on storage expressed in the previous comments. Overall storage available for videos per tenant with Stream (on SharePoint) in practical terms is more than Stream Classic. Here are some key points:
- Stream Classic was designed over 5 years ago with limited admin storage functions, when video demands were different to post-pandemic world.
- Moving to Stream (on SharePoint) we gain all the admin functionalities of SharePoint, using a system that is optimized for storing and manage corporate documents (files) in an efficient and compliant way. Here are some key differences related to storage:
- Classic had 0.5GB per user whereas Stream (on SharePoint) has 1TB OneDrive storage per user for all documents. While not all is for video in practical matters, if a user uses 1% of 1TB for video that is 10GB, which is 20x of the 0.5GB per user that was included with Classic.
- Classic included a baseline 500GB share storage for the whole tenant whereas Stream (on SharePoint) that baseline is 1TB + 10G per Licensed User (SharePoint limits - Service Descriptions | Microsoft Learn)
- With Classic we did not have a proactive way to manage storage like we have now with Stream (on SharePoint) we have this guideline: Manage site storage limits - SharePoint in Microsoft 365 | Microsoft Learn
- Stream (on SharePoint) supports Microsoft Graph. We had started seen IT Admins using Microsoft Graph to find, select, and manage video files. Another functionality that was not possible with Stream Classic.
- Regarding what happens to the OneDrive when a user leaves the company, there is a documented process to address this not only for videos but for any file--PowerPoint, Excel, Word, Visio, etc.--that users owned and how to reclaim ownership.
