Apart from being non persistent and scoped only to the current window, are there any benefits (performance, data access, etc) to Session Storage over Local Storage?
sessionStorage
maintains a separate storage area for each given origin that's available for the duration of the page session (as long as the browser is open, including page reloads and restores)
localStorage
does the same thing, but persists even when the browser is closed and reopened.
I took this from https://developer.mozilla.org/en-US/docs/Web/API/Web_Storage_API
