Revolutionary Technology
DroboPro™ is the first business class direct-attached storage array that manages itself. Engineered to be both simple and scalable, the revolutionary BeyondRAID™ technology incorporated into DroboPro frees businesses of making the difficult and confining choices commonly associated with storage management. Why trade simplicity for safety, or stability for expandability? DroboPro delivers both enterprise-level data safety and unprecedented expandability, featuring single and dual disk redundancy combined with instant capacity expansion.

Up to 8 Disks of Instant Expansion to 16TB and Beyond
Have a need for speed? With the new USB 3.0 interface on the Drobo S, data transfer is up to 50% faster than FireWire 800. USB 3.0 offers backward compatibility with all existing USB 2.0 systems, and the Drobo S features a triple interface with eSATA and FireWire 800 to ensure you'll have a high-performance connection for virtually any system.

No Headache Dual Disk Redundancy
Enable the Dual Disk Redundancy option to protect against the simultaneous failure of up to two hard disks. It's all done with a single click, without ever losing access to your data. Running out of space? You can even switch back to single disk redundancy with a click. For instance, unlike moving between RAID 5 and RAID 6, there's no need to reformat or migrate data off of the array, potentially saving you hours or days.
