The university storage challenge

I challenge all online, hardware and storage vendors in particular  too attend the university storage challenge!

At many universities around the globe there is need for massive amounts of storage. In general the storage solution has to have the following properties:

1. Be fairly  safe - some sort of redundancy is needed
2. Be fairly fast -we are talking about massive amount of storage so access time is not the priority, but the end user must not fall asleep. Ie transfer speed (read / write) should be equivalent to  USB 3 external hard discs. 
3. Have a life expectancy of at least 3 years. Some discs might need to be swapped but not so the storage integrity is damaged.
4. Be fairly scalable - we are basically talking about a huge amount of storage, that can be expanded when need arise
5. Be accessible by any computer via standard file access protocols (like SMB).
6. Have an extremely low price, at a maximum, equivalent to a USB 3 external hard disc.

The target price formula is simple! The price for 1 TB in the solution must be the same price as an external USB 3, 1 TB disc bought at your local hardware store, per year. Today that is around 800 SEK, €85 or $120. This means the price for 1 TB in the solution can cost no more than $360 when the system is bought i.e. a depreciation period of 3 years.

The reason for the price is simple, when talking to a professor it is hard to explain that our super duper good storage solution costs 10 or even 100 times more when they can go out and by one 1 TB disc at any local hardware store (or actually any larger supermarket). 

The expected use case is storage of end user files or other files (like massive data sets collected in a research project) where high speed or redundancy is not top priority. Basically it is a solution that rival an USB 3 external hard disc.

Are there any viable solutions out there? Either something on premise or in the cloud.
