New Synology Compatibility: DS418, DS418play, DS918+

A few of new Synology's just announced.

The DS418 which has a Realtek RTD1296 CPU, but unlike the DS418j does have a Hardware Transcoding Engine:

And the DS418play looks imminent:

Need to upgrade my aging DS410 and curious what the expectations are for Plex transcoding with these?

Thanks!
