The IT world develops extremely fast and the amount of data stored on storage arrays, as well as its value, increases exponentially. The traditional way of solving capacity and redundancy requirements is to pour money into the storage infrastructure. That is something that can be hardly achieved with commodity off-the-shelf hardware, so enterprise-grade storage arrays are kicked into the game, providing the ability to store large amounts of data while keeping it safe at the same time. This, however, is not the most suitable solution for SMB and ROBO scenarios due to its high implementation expenses and high total cost of ownership (TCO).
