Why Hubic; Because much has been done recently about issues of privacy, surveillance, security, and so on. it is good to know that there are some services cloud who do not face these problems.
Such a service is η Hubic, which is based in France, so it is not subject to US law and hence to NSA or anyone else's control.
A second point of excellence in the French service, as well as the issue of protecting our stored data, is indeed their competitive price. Specifically, if we enroll in the service, we will have 25GB free storage space. Then the charge starts from 1 per month for 100GB and if we want something more, for example 10TB, the charge is just 10 euros per month.
To have a size comparison, the 100GB in the OneDrive (formerly SkyDrive) cost 3 euros per month, while DropBox costs 7,5 euros per month. As for the large 10TB package, only Google's service offers something similar to Drive, charging 8 euros per month for 290TB.
Of course, the issue of reliability and know-how remains, but it takes time to prove it.
