Enterprise SSDs almost always include power loss protection capacitors on the drive itself, so the drive can either directly advertise that it's write caches are non-volatile or simply ignore cache flush requests from the host since data in the cache can already be considered durable from the host's perspective.

Unfortunately for this product, enterprise M.2 SSDs are almost always 110mm long rather than 80mm long, precisely because of the space taken up by those capacitors.
