Dropbox have just amplified their cloud storage and syncing offerings thanks to the increasing competition from Google, Microsoft, Amazon and others. Starting from today, Dropbox Pro subscribers will receive twice the storage space on their accounts, at no additional cost.

This means that those who were previously paying $9.99 per month, or $99 per year for 50GB of storage, will now receive 102GB of storage (100GB plus 2GB of free space that all users receive). Those who are paying $19.99 per month, or $199 per year will now receive 202GB instead of 100GB.

Dropbox are also offering any Pro members a 3-month 100GB trial to share with friends.
