What is a 308 Permanent Redirect HTTP response?
A 308 Permanent Redirect is a server HTTP response status code used (quite rarely) for permanent redirection.
A 308 HTTP response is near identical to a 301, and has been confirmed to be treated as such by Google.
The only notable difference between a 301 and 308 HTTP response is that a 308 does not allow changing the request method from POST to GET.

Is a 308 response good for SEO?
A 308 HTTP response has been confirmed by Google to be treated as identical to a 301 by its bots/algorithms.
However a 308 response is still a newer and more unusual status code, so it is unknown how all search engines/bots around the world will treat it.
Non-Standard Usage of 308 Status Code
It should be noted that some sites may use a 308 status code in a non-standard way, such as in Google Drive - where a 308 Resume Incomplete status is used to indicate when an incomplete upload has stalled.
