The Salesforce Lightning Inspector Storage tab is a tool that can be used to analyze and diagnose the problem of stale or outdated data in a Lightning page. The Storage tab shows the data that is stored in the browser cache by the Lightning components, such as reference data, metadata, and UI state. The developer can use the Storage tab to inspect the data, clear the cache, or disable the cache for debugging purposes. The developer can also use the Storage tab to monitor the cache performance and size, and identify any potential issues or bottlenecks.
