Salesforce Tips: Sandbox Storage
There are 2 types storage in Salesforce.
- Data storage : Record data in System and Custom object
- File storage: Attachment data
Each edition has its own storage limit stated here. Sandbox storage is somehow different from the normal edition. There are 3 different types of Sandbox in Salesforce:
| Type | Data Storage Limit | File Storage Limit | Free |
| Full | Same as production org | Same as production org | 1 included in Unlimited |
| Configuration Only | 500MB | 500MB | 5 included in Unlimited |
| Developer | 10MB | 10MB | 15 included in Unlimited 1 included in Enterprise |
For Apex development, Developer Sandbox should be sufficient. If you are testing integration with larger data set, you may consider getting a Configuration Only sandbox. Unless you need to replicate a full set of data from production org, you should not need the Full sandbox.
