Drobo 5D vs Pegasus R6

Direct-Attached Storage (DAS) refers to a digital storage system directly attached to a server or workstation, without a storage network in between. In other words the direct attached storage (point-to-point) on the server or computer. Storage DAS only directly accessible from the host where DAS attached. In terms of costs as well as the capacity of the storage media (hard disk), then the technology is still much cheaper compared to other technologies. So you should choose carefully before buying it. Make the Drobo 5 d vs Pegasus R6 as reference materials you further.

Drobo 5D
The Drobo 5D is a direct-attached storage device (DAS) with five 3.5 “carrier-less gulfs that have USB 3.0 and dual thunderbolt ports. Although in a design similar to the current Drobo model, 5D also adds many new features including: support for HDD and SSD, memory, faster processor and backup battery. Drobo designed 5D with media creations such as video and audio editor in mind understand the needs of high capacity, high performance devices. Drobo offers several other devices in the family like Mini which have the same features but with support for four 2.5 “drives, as well as 5N network attached storage devices (NAS). Drobo 5D benefits from a significant feature set. Uniquely, unlike most DAS devices, 5D has a bay below that can mSATA SSD for critical cache, often accessible data for performance improvement. Users can choose mSATA small capacity drives if their HDD is not a strong capacity, or they can swap with larger 128GB or 256GB mSATA SSD to heat up more significant performance. It also offers BeyondRAID technology with single or dual drive redundancy to provide data protection. In addition, drives can be swapped for direct expansion storage. Rounding out the features, there are two Thunderbolt Ports which one that supports daisy-chaining to allow users to take advantage of Thunderbolt speeds on their other devices.

Pegasus R6
Pegasus R6 appointment is the first Thunderbolt 2 peripheral to make its way to the Macworld lab. It is a six-drive 12TB hardware RAID box and can be purchased from Apple stores and so on. The R6 Pegasus2 we received has six 7200 rpm hard drives with 2TB of capacity each, capacity equal to the first Pegasus we tested. Pegasus2 is a hardware RAID that appears configured as a RAID 5 array, but can be easily changed to RAID 0, 1, 10, or JBOD using the included software. Pegasus2 has a black aluminum case to better match the new Mac Pro design and has two Thunderbolt Port 2 to allow daisy-chaining up to six compatible devices. Thunderbolt products with only one port should sit at the end of a daisy chain. Having two Thunderbolt Ports 2 gives you greater flexibility-you can connect more Thunderbolt 2 devices. Thunderbolt 2 is an update to the Thunderbolt specification which requires an original two 10 Gbps bi-directional channels and incorporates them into a single 20 Gbps bi-directional channel. The amount of data capable of moving through the Thunderbolt connection has not increased, but the throughput of one channel has been duplicated. Thunderbolt 2 is compatible with Thunderbolt devices, but the device will run at 10 Gbps slower speeds.

Both Drobo 5D vs Pegasus R6 are great DAS or Direct Attached Storage. The most important difference will be about Which one is faster. The Drobo we are thinking of getting is a 5D with the mSata 128 Card vs a 6 bay Pegasus 2. Any other idea about them? If you are doing the latter, how is the speed and is there any hangups?
