Most 4K video is closer to 50mbps. If your home connection is that fast, Sia should be more than capable of delivering smooth 4K streaming to your home.
A single host with slow storage is not a blocking factor because Sia downloads in parallel from as many as 30 hosts at once when composing a stream of data. Even if each has an I/O bottleneck of 1 MB/s (8mbps), you'll be able to get your video out at 240mbps.
In practice today, Sia hosts are almost all network bottlenecked, most use HDDs which do not have trouble keeping up with network latencies (HDD seek times are 11ms, network latencies usually 50ms+) or throughputs (HDDs can usually get close to 100 MB/s, far more than the network throughput)
Can I ask, have you tried streaming 4K video from the latest version of Sia? Seek times might be 5-10 seconds, but I believe that once your stream has loaded you will see completely smooth playback. Our next release has a focus on reducing those seek times, but the code is not ready yet.
No I have not tried it however, based on your information, this looks ideal for something like showing auto-playing video on a splash screen using your API to pull the file on the client side.
