actually the informations on the google workspace page are pretty annoying.
here its written clearly that workspace enterprise has unlimited storage:
on this new gdrive workspace site its written that on the enterprise ans business plans its unlimited storage if you have 5 or more users:
https://workspace.google.com/products/drive/
and here on the ToS
is an entry for " G Suite Business" (that should be our current plan right now or am i wrong?)
""G Suite Business" is an edition of Google Workspace comprised of all the Google Workspace Services, except Google Voice. Customers that have 5 or more End Users will receive unlimited Google Drive storage."
and for the Enterprise, likle written before:
""Google Workspace Enterprise Standard" is an edition of Google Workspace ... Customers that have 5 or more End Users will receive a total amount of Google Drive storage equal to 5TB times the number of End Users, with more storage available at Google's discretion upon reasonable request to Google."
