Hi @MS Techie ,
Thank you for the ask. Limit for storage account is 5 PiB (you can increase the limit by contacting Azure Support). Please check the link below for details.
- for overall Capacity, you can either go the Storage Browser or Metrics from the LeftPanel
- or you can go to the LeftPanel --> Containers --> click the specific container --> properties --> calculate size. Bingo! :)
Hope this helps! Thank you!
