According to the following link, shared Google Drives have a membership limit of 600 combined users and groups.

At my organization, we have a shared drive. We are unfortunately forced to share with users individually rather than create groups due to a conflict between organizational security requirements and our particular use case.
We are automating sharing using the Google Drive API, and we have a growing number of drive members which will eventually approach the 600 number. Is there a way we can find out how many drive members we have so we know if we're in danger of hitting the limit of 600? A user would be considered a member of the drive if at least one folder or piece of content anywhere on the drive had been shared with them. There doesn't seem to be a straightforward way in the Google Drive API to query the number of users that are members of the drive.
Thanks!
