If you have been using the unlimited storage feature of G Suite to back up your photos and videos, wait before moving into Google Workplace. Google Workspace only has unlimited storage on enterprise plans.
Google made some big noise about replacing the G Suite with an even better Google Workspace. Among the many changes that may or may not be incredible for you, one change is clearly not in favor of high storage users.
If you or your team were using G Suite Business, you would get unlimited storage for $12/user. If I recall correctly, you needed at least four users to enroll in that level of service. Now Google Workspace will only give you 2 TB of storage for your $12, 5TB for $18, and according to Android Police, you can move to an Enterprise account for $20 ($30 for enterprise+) and get the same unlimited storage. However, it will be at least 50% significantly more expensive.
