Working with a robot: Drobo in action
We've talked about the Data Robotics Drobo storage solution here on TUAW a few times, but there hasn't been a hands-on review of the device on this blog...until now.The Drobo is a mass storage solution that takes advantage of RAID -- Redundant Array of Independent Disks -- to provide a single large volume by combining two to four "naked" (not in an separate enclosure) hard disk drives. Drobo uses a proprietary system called "BeyondRAID" to do this while eliminating a lot of the administrative headaches that are normally associated with setting up RAID arrays.
Drobo uses a combination of RAID 1 (mirroring) and RAID 5 (striping) to provide relatively fast response times and redundancy. If a drive fails, you simply pop it out of the array and pop in a new one. Drobo takes care of rebuilding the new disk while the array is in use. While many traditional RAID solutions require all drives to have exactly the same capacity, you can mix or match drive sizes with Drobo. This makes storage growth quite easy to manage -- as new, larger capacity hard drives appear in the future, you just need to pull out a smaller drive or two and replace them with the larger drives. Drobo takes care of integrating the new disk or disks into the array. Click the Read More link for the rest of this post.
