Actual, real world, interface speeds and ranges: Wifi, USB, Ethernet, SATA, Bluetooth [CHART]

This chart can be very useful if you’re trying to figure out where a speed bottleneck is. The actual speed of actual data is usually quite different then the protocol limits for many reasons, on many levels. For instance, although USB 3.0 and SATA III have fairly similar speeds at 5Gbps and 6Gpbs respectively USB is MUCH slower due to many factors including; lanes of data, software protocol, and cable construction. SSDs speeds vary incredibly, you have to benchmark them, or trust the manufacturers claims. RAM speeds are usually not the bottleneck.
Unfortuneatly, marketing also gets in the way of figuring out actual speeds. Especially with WiFi or powerline.

Help me by updating the chart here:…
