I've seen a few products recently that promote the idea of hosting video files on Dropbox. There was a even plugin that made it possible a few weeks ago.
I suspected it would be easy to trigger the bandwidth limits Dropbox impose so I did a test. I hosted just a couple of my videos on Dropbox...
Within 10 days this had happened (and I am on a Pro paid account with higher limits):
At the end of the day Dropbox is for sharing files within a small group. It is not a hosting service.
If you host video or digital downloads you sell on Dropbox you are asking for trouble.
- For file and video hosting Amazon S3 is cheap. It takes a little getting used to, but it works great.
- Use SnakePlayer and host your videos on YouTube. By doing this you have unlimited, massive bandwidth but maintain control over the branding and can make your player match your site.
- Host them on your own server. If you use VPS hosting the speed won't be an issue, but do check your monthly bandwidth limits.
