Drobo 5D3 External HDD Overview

This B&H Kit combines the Drobo 5D3 5-Bay Thunderbolt 3 Enclosure with five Seagate 8TB IronWolf 7200 rpm SATA III 3.5" internal NAS hard drives, for a total storage capacity of 40TB.

Drobo 5D3 5-Bay Thunderbolt 3 Enclosure

Designed for media professionals, content creators, and small businesses running Apple Final Cut Pro, Adobe Lightroom, and other I/O intensive applications, or even those who just need to back up terabytes of data, the 5D3 5-Bay Thunderbolt 3 Enclosure from Drobo is equipped with five 3.5" SATA drive bays that support SATA III 6 Gb/s and SATA II 3 Gb/s drives. The 5D3 distinguishes itself from the original Drobo 5D and 5Dt through the inclusion of Thunderbolt 3 technology, which is accessed through two integrated Thunderbolt 3 ports. While one of the Thunderbolt 3 ports is used to connect the 5D3 to your compatible system, the second one is used to daisy-chain up to six Thunderbolt devices together, including one 5K display or two 4K displays. The Thunderbolt 3 ports also provide 15W of charging power for Thunderbolt 3 laptops, and there is also one USB 3.0 Type-C port, which transfers data at speeds up to 5 Gb/s. Please be aware that the 5D3's Thunderbolt 3 ports are only compatible with Mac, while the USB 3.0 Type-C port can be used with both Windows and Mac. Mac support includes APFS/macOS High Sierra.

To help complement the speeds of Thunderbolt 3, the 5D3 has been built with Drobo's Accelerator Bay, which uses an separately sold mSATA SSD to boost system performance. It accomplishes this by placing data that is read or written into SSD storage. When the data is active, it is stored in the SSD and will be moved back to the hard drive tier as its use decreases.

To facilitate data protection, Drobo's BeyondRAID technology enables single or dual-drive redundancy. If there are any empty drive bays, BeyondRAID allows additional drives to be inserted into the array, where they would be automatically configured. If all drive bays are occupied, simply replace the smallest capacity drive with a larger one and BeyondRAID will handle the rest. BeyondRAID is also what allows drives of varying capacities to work in the same unit, which helps enable future expansion as larger drives become available.

Additional data protection is provided by the included rechargeable battery, which helps protect data stored in the 5D3's cache. If there were to be a sudden power loss, the battery allows the Drobo to stay powered long enough for the cached data to be written to non-volatile storage. Cooling is provided by a 120mm variable-speed fan and once installed, the hard drives can be configured to spin down when they're not in use, helping to further reduce noise and energy. Also, the LEDs can be dimmed to reduce light pollution when working in sensitive environments. The Drobo 5D3 also includes a 3.3' Thunderbolt 3 cable and a 6.0' power cord with a power supply that operates using 100-240 VAC at 50-60 Hz. Protection is provided by a limited 2-year warranty.

General Features

Data Protection and Expandability

Built on award-winning BeyondRAID technology with single- or dual-drive redundancy, the Drobo 5D3 protects your data without any user interaction, even in the event of multiple drive failures.

Drives can be added or hot-swapped and updated in real time 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. Consult the online capacity calculator to determine how the choice of drive size, number of drives, and protection levels affect available capacity.

The Power of Thunderbolt 3 and Flexibility of USB Type-C

Thunderbolt 3 technology provides performance that's twice as fast as the previous generation. This optimizes your performance when transferring large volumes of data.

The Drobo 5D3 is equipped with dual Thunderbolt 3 ports for daisy chaining on Mac only. Connect up to six Thunderbolt devices and/or a non-Thunderbolt monitor at the end of the chain. The 5D3 supports one 5K monitor, two 4K monitors, and 15W of power for device charging. By having 5D3 arrays in a chain, you can have up to 300TB of usable capacity and achieve throughput by enabling the bi-directional 40 Gb/s performance of Thunderbolt 3. It is compatible with systems running supported versions of Mac OS X, including APFS/macOS High Sierra, as well as Windows, with Windows compatibility only available using the USB 3.0 Type-C port.

Enhanced Time Machine Support

Drobo is compatible with Apple's Time Machine, which will consume the capacity of an external storage system. By utilizing the Drobo Dashboard, you can simply allocate capacity limits for backups and data storage.

Capacity and Performance

The Drobo 5D3 includes a built-in Accelerator Bay, with an mSATA card holder (mSATA card not included). Their patented Accelerator Cache technology keeps a copy of your most frequently accessed data to deliver fast speeds. The accelerator cache can dramatically speed up loading large photo libraries and other I/O intensive operations, smoothing out workflows allowing you to optimize productivity for applications such as Apple Final Cut Pro X and Adobe Lightroom.

Power Protecting Your Critical Data

Drobo doesn't just protect you from a drive failure, but also from potential data loss after a power outage. Often found only in arrays that cost tens of thousands of dollars, the Drobo 5D3 includes a battery that protects all data in the memory, or cache, that is, data on its way to the drives.

During a sudden power loss, the internal battery keeps the Drobo alive long enough for the data to be written to non-volatile storage. The battery recharges itself and lasts for the life of the product.

Drobo Dashboard

Drobo Dashboard is the single tool used to centrally manage all of your Drobo devices. Drobo Dashboard displays status as if all of your Drobos were right in front of you with the same status lights and capacity gauge that are on the front panel. All administration tasks are a single click away.

Designed for You

Drobo devices have always been space efficient and the Drobo 5D3 is no exception. It is designed to provide high capacity, without taking up a lot of your valuable desk space. It is compact because of Drobo's carrier-less drive bay design, allowing drives to be installed very close to each other. Users can also dim the lights and configure drives to spin down when not in use. Included is a Thunderbolt 3 cable.

This is not something that is published by the manufacturer as it can change at any point. If you are wanting specific drives it would be best to buy the Drobo 5d3 without drives and add on the drives you would like. Drobo 5d3 with out drives : https://bhpho.to/2sQsYVB

If the unit has 5 bays then why does every configuration come with only 4 drives?
Asked by: Jordan
The 5th bay is for a cache drive, in the case of RAID mirroring, it is optional for RAID use and speed. For JBOD use, a 5th drive can be installed there for extra capacity.

Does anyone really feel the speed difference between the 5C (USB C) and the 5D Thunderbolt 3 model is worth the cost difference?
Asked by: matthew
Hello, The Drobo 5D3 with Thunderbolt 3 is a faster model than the Drobo 5C. There are several improvements from the processor to the general speed capability of the Thunderbolt 3 ports with macOS (only) products, as well as the accelerator bay at the bottom of the Drobo 5D3 for an mSATA card to use as cache data. So the additional expense is worth it if you handle large files, want to use the Drobo as a working drive and use macOS products. Also, note that for better performance use high-performance Hard Disk Drives that are 7200 RPMs. Best, Team Drobo

I just received my 5D3. I already have a 5D (previous generation, Thunderbolt 2), connected to an older MacBook (also Thunderbolt 2). The 5D3 only has Thunderbolt 3 inputs, and comes with a Thunderbolt 3 cable, which I cant use. What do I need to fit the 5D3 in with my 5D and MacBook? Is there a cable that is Thunderbolt 3 on one end and Thunderbolt 2 on the other? And, does it matter which Drobo is first in the chain? Thanks!
Asked by: Glenn G.
In order to make this work, you would need to use the Apple Thunderbolt 3 Male to Thunderbolt 2 Female Adapter. It is bi-directional and will work when daisy chaining drives as long as you are running at least OSX 10.12.13. The adapter should be used with the first drive in the chain.

Will this item support access to same data from both Windows 10 pro and Mac OS at different times?
Asked by: David
The Drobo 5D3 5-Bay Thunderbolt 3 Enclosure (Gold Edition) B&H # DRDR6A21G can only be accessed by one computer at a time. If you are looking for a device with those capabilities, I suggest looking at the QNAP TS-453BT3 4-Bay NAS Enclosure B&H # QNTS453BT38G. It supports both NAS and DAS functionality.
