Earlier Gsuite account has unlimited storage space, can store even more than 100TB in it.
Now, Google has changed these in Google Workspace, now users will get from 2-5TB disk space in Business Plan.
New rules are currently applicable for new Google Workspace accounts only.
Old Gsuite accounts are still have unlimited storage space, But google may be rolling out these to old account in coming days/months.
Google have not provided any info for old Gsuite accounts, yet., But It will take time for Google to roll out the new changes to old Gsuite accounts., if they roll out to old accounts too,
Even in the new Plan, users will get 2-5TB disk space in Gsuite/GWorkspace Business Plan. so there should not be any issue if using under 2-5TB disk space..; (users using more than 2-5 TB disk , may require multiple accounts to store high amount of data. )
Currently the changes are for new accounts only; Our Gsuite accounts (& old Gsuite accounts) still have old features and unlimited storage space.
We will inform here, for updates/changes related to our Gsuite accounts.
