Dropbox

Dropbox

Dropbox is founded by Drew Houston and Arash Ferdowsi in 2007

Dropbox is a service product that allows you to store, sync, and share your data on the online server, so that this service helps you to get your data quickly, easily, and for the most elegant of almost any Internet-enabled devices [31]. Of course, your data is stored with strong encryption on multiple servers. Dropbox also allows you to access your data using a computer or device you have on hand. Therefore, if you miss important file while travelling, it will not prevent your working life anymore.
Dropbox is a downloadable product that can be downloaded directly from the company’s website and only available there. It has a version for every major operating system, like Windows, Mac, Linux, iOS, Android, and BlackBerry. If you are in the computer or any other device that does not have Dropbox installed, you can access it via the Dropbox website (www.dropbox.com) that has a simple look of interface.
To see all the data that exist in your Dropbox, you must login into your personal account first. Any changes that you make from your main computer or other device will be synchronized quickly. Dropbox will tell you if there are any changes that occur in your files, and it also tells you whether the changes made from your main computer or other device without mention an IP address clearly. In addition, the Dropbox also stores files that have been deleted from the web interface. So, if you delete a file, it does not mean the file has been permanently deleted until you purge it.
Dropbox offers several different pricing levels. It gives you free for 2 GB of storage for one user, $9.95 per month for 50 GB of storage (Dropbox Pro 50) for one user, $19.99 per month for 100 GB of storage (Dropbox Pro 100) for one user, and $795 per year for 1 TB of storage for up to five users (this package includes telephone tech support).

The number of Dropbox users from year to year has increased quite impressive. According to [32], at the end of 2009, Dropbox has about 2 million users. One year later (2010), the number of users increases to about 4 million people. Then, before April 2011, the company has about 25 million users and 200 million files ‘saved’ per day and more than 1 million per five minutes. And by source [33], in early October 2011, Dropbox has had more than 45 million users and has been storing data 1 billion every three days.
