It has been 9 years since I reviewed the DroboPro. For its time, that product was a beast of a device, with the closest to a set it and forget it RAID implementation I had ever seen. It was also robust enough to shrug off any combination of power loss and pulling (failing) disks that I could throw at it. The ease of use/durability combination was a good formula for Drobo that has now lasted over a decade. The main hurdles over the years have been more on the performance side of things. The original DroboPro was indeed quicker than previous Drobos and other competing models, but competition quickly surpassed them in performance. Later Drobo models brought decent performance and capabilities for competitive prices (like the Drobo 5C), but we havent had a worthy successor to the original DroboPro. They came close in the form of the B810 series, but those were still limited by Gigabit links.
