We don’t want you to worry about choosing the right plan or having enough space. So today, we’re simplifying Dropbox Pro to a single plan that stays at $9.99/month, but now comes with 1 TB (1,000 GB) of space.
They've matched Google Drive on the 1 TB monthly plan. Dropbox still offers the $99 annual plan, so it's actually cheaper than Google Drive if you pay annually. They've also released a number of new (and much appreciated) features.
