Redesigned from the ground up to meet the data storage needs of today's media creators and demanding professionals, Drobo 5D builds on the fully automated functionality of previous Drobos by adding blazing-fast performance. Leveraging cutting-edge Thunderbolt and USB 3.0 connectivityalong with the innovative use of solid state drives (SSDs) Drobo 5D is the highest-performing personal storage array on the planet. Not only is Drobo 5D fast, but it's easy-to-use, expandable, flexible, and protectedexactly what's expected from a Drobo. You can safely store and edit photos and videos as well as store and back up personal data. SDR and DDR on the Drobo 5DBuilt on award-winning BeyondRAID technology with single- or dual-drive redundancy, Drobo 5D protects your data without any user interaction, even in the event of multiple drive failures. Drives can be added or hot-swapped on-the-fly for storage expansion with zero downtime. If you're running low on space, the lights on the front tell you what to do. Just add a drive in an empty bay or remove a smaller drive and replace it with a larger one.Power of Thunderbolt and Flexibility of USBThunderbolt I/O technology provides performance that's up to 5x faster than the previous-generation Drobos. This allows you to move large amounts of data in a fraction of the time it used to take. Visit the Thunderbolt technology site to learn more about this exciting new way to connect devices. Drobo 5D is equipped with dual Thunderbolt ports for daisy chaining. Connect up to six Thunderbolt devices and/or a non-Thunderbolt monitor at the end of the chain. With six Drobo 5D arrays in a chain, you can have up to 96 TB of usable capacity. And, the bi-directional 10 Gbps performance of Thunderbolt allows all devices in the chain to achieve maximum throughput. Drobo is the only storage array that offers Thunderbolt AND USB 3.0. This latest generation of USB also offers high-performance connectivity and is backward compatibility with any computer running compatible versions of Mac OS X or Windows. Capacity and PerformanceData-Aware Tiering technology, usually reserved for business-class storage solutions, is also available in this desktop Drobo. It intelligently uses the high-performance flash in SSDs to accelerate performance of the storage array, allowing applications such as Adobe Premiere and Apple Aperture fast access to data. To keep capacity of the Drobo at a maximum, the Drobo Accelerator Bay accepts an industry-standard mSATA SSD, leaving all five 3.5" drives bays available for high-capacity HDDs. If getting the fastest performance possible is your thing, you can also load up every drive bay with SSDs. Drobo gives you the flexibility to choose.
