Based on functionality each NAS has, you can see that Synology is made with the home user in mind. WD is more about reliability rather than entertainment, which makes it more like business NAS. Both NAS have similar CPU performance. Even though DS418 CPU looks weaker, it still has 4 cores rather than 2. That really helps in a multitasking environment. CPU also has encryption and video transcoding engine built in. That really helps when NAS has a multi-purpose use case. You can still do other tasks even though there are encryption or video transcoding tasks running.

DS418 also has new generation DDR4 RAM which is faster than predecessor DDR3. Synology has several fn modes and light brightness adjustments available. That is very handy when NAS is located at home- especially in the living room or bedroom. Synology also has a much wider selection of available apps to download and install. WD is rather limited to few business-related apps and 1 multimedia app which is Plex. If plex is what you need it for – DS418 is not an option. Currently, its CPU is not supported.

WD NAS has dual power supply technology. That is a very business-like feature. If many people rely on NAS services, the broken power supply would mean chaos between users urgently needing an access to a drive. Also, 3 years warranty helps to put the mind at ease. It is one year longer than Synology, but only if prepopulated NAS is purchased. The last highlight would be WD expandability option- Synology does not offer that for this model.

So, if NAS is for Plex and file storage- the answer is WD. If Plex is not important, I would suggest DS418 or DS418play.
