It's faster, but only under the specific design condition of both having to wait for storage to finish and not caring about differences between the presented storage options.

If the design condition allows asynchronous operation and I don't need to wait for background tasks to finish before I reply, it's not faster unless I somehow care more about background CPU time per request than I do about things like storage guarantees.

If the design condition requires durable storage to have happened before I reply, putting it in Redis doesn't even count as getting started.
