Google Drive offers the same size for the same price. I don't see why anyone would use you when a) they can't be sure to trust you b) your service may not last as long as its paid for. Comparatively, with Google at least one can be sure that your files won't randomly disappear or they'll run off with funds.
a) OK,we have added more space for the same price. That is fair. You don't need to trust us, but you can trust the SourceCode.
b) 50GB encrypted Cloud Space for free. If you find a similar Service tell me.
c) We using a Server Cluster and add everyday more than 200TB.
The database cluster (#1) which holds all databases on SSD servers, the email cluster (#2) which is responsible for all email communication and the webcluster (#3 - #6) which is described further.
When you visit our website you are first directed to one of our load balancers (#3). A load balancer distributes the oncoming website calls to different webservers (#4) depending on the current workload of each webserver. This allows us to have the maximum performance since the calls are distributed over all of our webservers. Furthermore this also allows us to reboot single webservers for maintanance or shut them down for hardware upgrades without you even noticing it. The load balancers will redirect your request to a different webserver node. This means that we can achieve high availability and our website is online all the time.
For the webserver nodes to access our website there needs to be a centralized storage (#5) in the background. The storages we use are high qualitive ones with lots of harddrives, different disk types (SSD, SAS, SATA II etc.) and multiple backplanes. This allows us to scale to our needs and assure that the distributed data will be available all the time. For all of our security checks and the management of our cluster there is a control unit (#6) that monitors the health of the cluster all the time.
That is how our Server works and all data is with AES256bit encrypted. We also use end to end encryption.
