A common misconception about video streaming is
that it doesn’t use up as much data as downloading the same video would. In
fact, it uses about thesame amount of data.
You often end up using more. When streaming a video, the file buffers ahead
of time. This is the segment of the film that you have downloaded.
Unfortunately, if you refresh the page, or close it down and come back later
to re-watch it, chances are you'll have to download it all over again.
We logged how much data YouTube uses for a 5 minute video, using the more
common resolutions.
Here is a table of the speed at which each video downloaded, as well as the
amount uploaded per second and the final amount of data that had been
downloaded.

Bits per second (up) 5-9Kb 15-20Kb 20-26Kb 320Kb 320Kb
Data used in 5 minutes 8.3MB 13.3MB 20MB 37.5MB 62MB
720p is the lightest form of of 'HD' and is a popular resolution. For every 5
minutes of 720p video footage on YouTube you're using up around 37.5MB of data.
In 2012, the average YouTube viewer watched 6 hours of video per month.
YouTube has since stopped publishing this statistic, but does claim that the
number of hours watched by users
goes up by 50% annually.
At 720p that long-surpassed 6 hours would have come to around 2.7GB of usage.
This is a drop in the ocean for a big 100GB cap, but something smaller like a
wireless 3G or 4G plan it can be devastating.
It also goes beyond YouTube. Videos are embedded in everything from online
newspapers to review sites and even Facebook. It all adds up, so be mindful if
you have a limited cap when it comes to video content.
