Google:

We remain committed to providing all institutions around the world with a best-in-class experience, including ample free storage to support quality educational experiences. The new storage model will provide schools and universities with a baseline of 100TB of pooled cloud storage shared across all of your users — more than enough storage for over 100 million docs, 8 million presentations or 400,000 hours of video. This policy will go into effect across all Google Workspace for Education editions for existing customers in July 2022 and will be effective for new customers signing up in 2022. To empower admins to adapt to this model and optimize their storage, we will provide tools to identify and manage how storage is used and allocated far in advance of the policy going into effect.
