Features

Consumer Mindset, Enterprise Feature Set.
Drobo was designed to meet a stringent design requirement: Anyone should be able to use Drobo regardless of technical experience. It is ready to go out of the box and will always stay that way. Drobo does all the work of managing an enterprise-grade your storage system for you.

No Software or Drivers are Needed!
The Drobo magic comes from the software that\'s built into the hardware called BeyondRAID—an advanced storage technology. Drobo does everything for you from expanding capacity when you add a drive, to self-healing around drive failures and data errors. Drobo also includes a powerful desktop software utility called Drobo Dashboard that shows you what Drobo is up to and adds important functionality including firmware updates, formatting options and email alerts.
