There are several reasons why you could prefer Wuala over dropbox.
First of all Dropbox has a general problem with security due to its design. In addion there have been other issues, like the Authentification Bug in June 2011 or troubles around the terms of service.
Wuala takes a complete different approach on security. The files are encrypted (AES) and split up into multiple chunks on the client side and afterwards transferred to distributed datacenters. There are several other points why Wuala is a strong alternative to dropbox mentioned on lifehacker.
If you install Wuala via this referrer link you start with 2GB instead of 1GB.
Several other promo codes increase your starting space:
PC-MAGAZIN (2 GB)
I-KNOW-MARCEL (1 GB)
I-KNOW-FABIUS (1 GB)
I-KNOW-DOMINIK (1 GB)
I-KNOW-CAROLA (1 GB)
All these codes expire after 1 year!
Another surplus over dropbox is that you’re able to share some of space of your harddrive. Depending on the amount of space and your online time you gain additional space. You could even install the Wuala client (java) on your dedicated root server and donate some space in order to get the same amount (in my case 50G) of space for your account..
The Wuala Client is available for Linux/Windows/MAC. The recent updates to the mobile clients were necessary and the new iPad Version is also available. In addition the usual iOS/Android Client wait’s in your appstore.
For small and medium sized companies the guys from LaCie grant a decent business offer: 279€ for 100GB and 5 user per year.
The downside of Wuala currently is that it’s not as easily managed as dropbox and that the client isn’t integrated as deeply as dropbox into your operating system.
