Most of our growth is word of mouth/viral, so free users are still valuable: we grow faster, and they refer people who might pay.
Picking the right duration is tricky, and people add files to their Dropboxes at different rates. Many pay eventually after using the free service for a long time.

Dropbox is a file hosting service operated by Dropbox, Inc., that offers cloud storage, file synchronization, and client software. Dropbox allows users to create a special folder on each of their computers, which Dropbox then synchronizes so that it appears to be the same folder (with the same contents) regardless of which computer is used to view it. Files placed in this folder also are accessible through a website and mobile phone applications.
Dropbox, Inc., was founded in 2007 by MIT students Drew Houston and Arash Ferdowsi, as a Y Combinator startup company.
