Synology DS416play 4-bay NAS Review
 

DS416play 4-bay NAS from Synology is another multimedia-oriented model, which is able to transcode 4K videos in order to play them back on many other portable devices linked to the network and this is possible thanks to the hardware transcoding engine present within the included Intel Celeron N3060 dual-core CPU. This one is paired with 1GB of DDR3 memory, which should be enough for a home server and the four bays do support HDDs with capacities up to 10TB (for a maximum of 40TB): that is a lot of storage for many 4K videos and other stuff!
