Hello @Jaison DSouza B ,
It is possible to get unlimited storage for Microsoft OneDrive.
You can check the storage pricing at this link : https://www.microsoft.com/en-us/microsoft-365/onedrive/compare-onedrive-plans?activetab=tab:primaryr2#coreui-contentrichblock-bo9forg
If you need unlimited storage, then the OneDrive for Business (Plan 2) should suit you.
Bellow are some of the conditions :
Unlimited individual cloud storage for qualifying plans for subscriptions of five or more users, otherwise 1 TB/user. Microsoft will initially provide 1 TB/user of OneDrive for Business storage, which admins can increase to 5 TB/user. Request additional storage by contacting Microsoft support. Storage up to 25 TB/user is provisioned in OneDrive for Business. Beyond 25 TB, storage is provisioned as 25 TB SharePoint team sites to individual users.
