Frequently asked questions
You need about 667 Mbps to download 50 GB in 10 minutes. That requires a gigabit fiber connection. At a more common 100 Mbps it would take about 67 minutes instead.
A typical 1080p movie is about 4-8 GB. To download 8 GB in 5 minutes you need about 213 Mbps. For a 4K movie at 50 GB in 5 minutes you would need about 1.3 Gbps.
To transfer 1 TB in 8 hours you need about 278 Mbps. For a more comfortable 12-hour window you need about 185 Mbps. Most fiber plans can handle this easily.
Streaming 4K typically requires 25-50 Mbps sustained. Netflix recommends 25 Mbps for 4K and YouTube recommends 20 Mbps. Real-world connections should be at least 50 Mbps to account for fluctuations.
For casual use 100 Mbps handles most downloads well. For frequent large downloads like games or 4K media, 300-500 Mbps is ideal. For near-instant transfers of very large files, gigabit fiber at 1 Gbps or higher is best.
