With four drives, we measured <40dB at the rear of the twin 92mm fans.
Drive heat was 29°.
We measured approx. 50Wh use, regardless of load or idle. I guess NAS needs to be always on.
We need to clarify that the NAS can do transcode 4K video to 1080p or lower streams that can go over 1Gbps (100MBps) LAN. It does not have an HMDI or DP output for direct-to-TV multimedia. It does support HDR and Atmos sound streams. If you are considering it for 4K, then read this.
What the means is that you don’t have to use a separate software codec or player. For multi-media use, you would be best just using it as a network DLNA drive and letting the 4K TV do the decoding.
GadgetGuy’s take – Synology DS-918+ has cache which helps more users and larger files
Sorry if this review is not too techy because it is all about letting readers know that small business and home enthusiasts that store a lot of data can but a good quality NAS with cache for a reasonable price.
When I was providing tech support, I installed several Synology NAS into networks, and the user response was profound. “Where did that file go?” or “Love that auto backup and sync.”
There are lots of NAS brands, but Synology stands out as a no-nonsense design with a very high number of aficionados who can make it sing.
