Data Robotics Drobo Storage Robot EnclosureIf you're passionate about creating and collecting digital content, but not about storing it, we've designed the Drobo Storage Robot Enclosure just for you. The Drobo is the first storage system to take the pain out of keeping your content safe. Avoid the hassles of complex RAID setups or managing multiple external hard drives. Attach Drobo to your Mac or PC and let it manage your storage needs, so you don't have to. Combine four hard drives into one large storage pool. You can start with two drives, then move up to four. Upgrade drive size, speed, even manufacturer at any time. Mix and match as you need, or as you like. Drobo—it does everything for you.
