As per Salesforce,
Full copy sandboxes have the same storage limit as your production organization.
I want to know what is the "storage limit" exactly, just like for Config-Only sandbox, it is 500 MB, for developer sandbox, it is 10 MB. What is it for Full-Copy Sandbox?
Also, I have heard that each record's storage size is 2 KB. Please confirm if this is correct and also let me know accordingly, how many maximum records can exist in a Full-Copy / Production environment.
