Synology DiskStation DS224+ vs. TerraMaster F2-223: Which NAS is best?

The Synology DiskStation DS224+ and TerraMaster F2-223 are two popular two-bay NAS enclosures. We've taken both servers for a test run to see how good they are at storing files on a network, streaming (and transcoding) media, and transforming your home or office. They have two drive bays, an Intel Celeron processor, DDR4 RAM, and various USB and LAN ports. Either NAS would make for a good starter enclosure, though the DS224 is the more expensive choice and the F2-223 has a slightly rougher user experience.
