Bandwidth
Data transfer includes all traffic that passes through a web hosting provider’s core routers, including FTP and email. Colocation packages normally include either 1Mbps or 5Mbps burstable connections, measured on the 95th percentile. A 10Mbps connection relates to approximately 3.3 Terabytes of bandwidth monthly.
To determine estimated monthly bandwidth for your site, first determine the page size for each page of your website, then estimate how many daily pageviews you project for each. Simply multiply to estimate monthly bandwidth forecasted, allowing for some overhead.
Note: A two (2) minute video can easily consume 10MB of bandwidth. As little as 300 downloads per day of that one video can consume 90GB of bandwidth monthly.
