Using a Google Chromcast with Kodi (SMB) and an Android tablet also with Kodi (SMB) I was able to stream a 1080p movie with AC3 audio stream to both devices without hiccup (~8Mb/s streams both accessing the same file). That is plenty good for me. Then on my home PC I streamed 3 movies on Potplayer (bit rates between 3-8Mb/s) also no issue at all. I have some 20+Mb/s files I haven’t tested yet, but I can always reencode these to a more manageable bitrate.
Idle power consumption with the 1TB SN770 attached in the USB to NVMe enclosure is only 5.5W. Under load with three streams going the max I measured is 6.5W, which is perfect for my use case.
Overall very happy with this router. Will setup NordVPN next and assign the switch to the wireguard profile.
