I have been looking at profiles in my organization and I notice that on some objects profiles have both read and view all permissions on a single object. Wouldn't having read and view all be redundanat and be the same as having just view all? Could someone help me to understand why a profile would need read and view all permissions on an object, instead of just having view all?

Hi All,

Currenty our data storage limit exceeded and looking for an option to storage some data outside salesforce and only read/display them in SF. Would like to know various options/suggestions from you. 

Thank you!!
