"For streaming services like Netflix, YouTube, and Amazon you’ll likely want to have at least 25 Mbps. If you’re only going to be downloading 4K content from sites like MGO or Ultraflix, 10 Mbps will probably suffice. In any event, fast and reliable Internet is an integral key to a positive streaming experience."
