The Drobo 5D is a rather unique storage solution, and for the longest time, I myself wanted to get my hands on one. The 5D is a five-bay direct attached storage appliance or DAS for short, which offers both USB 3.0 support for Mac OS X and Windows operating systems, but the real magic is found within the dual Thunderbolt ports, which at this time only work within Mac OS X.
The Drobo 5D was designed around creating a storage solution that was easy to use, offered data protection, and the performance creative professionals need and demand. The Drobo 5D does this by offering the latest in BeyondRAID technology coupled with SSD caching to increase performance. BeyondRAID is a rather unique feature that Drobo has went all in developing.
In traditional RAID arrays, when you want to change RAID levels say from 5 to 6, you would have to dump the data and reinitialize the array and move your data back. With the technology of BeyondRAID, if you need to add storage capacity, you just pull a drive and replace it with a larger one and the Drobo recognizes and adds the new capacity to the storage pool, without any user interaction. If you want additional redundancy similar to what a RAID 6 offers, it's the click of a button and the Drobo takes care of it.
The Drobo 5D has an included two-year warranty, which then can be extended to three years via DroboCare. The five-bay Drobo 5D is available is available in both 6TB and 15TB capacities with prices ranging from $1099.99 to $1699.99, and in addition to this, Drobo offers the 5D in a diskless solution for $699.99.
