As of tomorrow (15th May 2014) Box is removing storage limits for all current and future customers on their Business and Business Plus plans. So if you have Box Business Edition, you can now enjoy the same unlimited cloud storage as Box Enterprise customers.
Back in 2010, Box made storage unlimited for Box Enterprise customers and later raised Business plans to one terabyte, but they have decided to remove storage as a consideration to enable organisations to focus on the business value and functionality that best meets their needs, rather than worrying about reaching storage limits.
Box is an innovative cloud file sharing solution that eliminates the need for cumbersome, on-premise file storage systems. The Business Edition is designed for firms that have a minimum of three users and offers a simple per-user monthly charge.
