I’m using an Omni mobile 25600 and it’s awesome.

Best bet would be its fast to store and edit across the network, but it isn’t really a requirement. You could simply store the media on your local PC, edit it there, then before going to bed start a copy over to the NAS and have it complete by morning. Obviously 10Gb/e would be faster, but i don’t see it as a requirement.

Would 100% go JellyFin vs Plex, also toss in some sonarr/radarr automation and organization. Everyone should have some kinda media streaming server, even if its just kept in house.
