When signing up you get 2GB of space free as well as peace of mind that your data is safely stored in the event of losing your laptop or the hard drive crashing. Dropbox implements stringent data security measures and your files are encrypted, making it a secure, highly useful resource for entrepreneurs. Most small business owners can use Dropbox for free indefinitely but for those businesses that are data intensive, Dropbox offers an affordable rate of $99 per year for the provision of massive storage space.
