AKiTiO Thunder3 Duo Pro
External Thunderbolt™ 3 & USB 3.1 Gen 1 Storage Solution
This dual bay RAID storage enclosure can reach data transfer speeds of up to 785 MB per second while simultaneously providing two 4K video signal streams. For added convenience and flexibility, the AKiTiO Thunder3 Duo Pro can accommodate both 2.5-inch and 3.5-inch drives. It is completely "tool-less", so drives can be easily installed or uninstalled.
Thunderbolt 3 for lighting fast transfer speeds up to 40 Gbps
Triple connectivity featuring Thunderbolt 3, USB 3.1 Gen 1 and DisplayPort
Second Thunderbolt 3 port supports Thunderbolt 3, USB 3.1 (10 Gbps), and DisplayPort devices
Hardware RAID controller (RAID 0, RAID 1, SPAN, Non-RAID)
Tool-less drive installation for 2.5-inch and 3.5-inch drives
Built-in fan for active cooling with power switch
Dedicated DisplayPort for additional 4K monitor
Kensington security lock slot
Thunderbolt 3 brings Thunderbolt to USB-C at speeds up to 40 Gbps, creating one compact port that does it all – delivering the fastest, most versatile connection to any dock, display, or data device. For the first time, one computer port connects to Thunderbolt devices, every display, and billions of USB devices. A single cable now provides four times the data and twice the video bandwidth of any other cable, while also supplying power.
The second Thunderbolt 3 port on the AKiTiO Thunder3 Duo Pro operates the same as a Thunderbolt 3 computer port by supporting Thunderbolt 3 (up to 5 daisy chained), USB 3.1 (10 Gbps), and DisplayPort devices.
USB 3.1 Gen 1
To assure backwards compatibility with systems that only offer USB connectivity, the AKiTiO Thunder3 Duo Pro also comes with a SuperSpeed USB Type-B port. This interface is also known as USB 3.1 Gen 1 or USB 3.0 at speeds of up to 5 Gbps.
The dedicated DisplayPort connector makes it easy to connect an additional monitor to extend your workspace. This video output capability requires a Thunderbolt 3 connection to the computer and will free up the second Thunderbolt 3 port for Thunderbolt 3 (up to 5 daisy chained), USB 3.1 (10 Gbps), and DisplayPort devices.
Hardware RAID Controller
Optimized for every environment
With the built-in hardware RAID controller, the choice is all yours! You can mirror the drives with RAID 1 as a reliable backup for your important data, you can stripe the drives with RAID 0 for optimal performance and maximum speed or you can select SPAN to combine the drives for extra large storage capacities.
OS independent RAID set
A big advantage of the built-in hardware RAID controller is that the RAID set is OS independent, so the storage drive can be moved from one system to the other with ease. Because the RAID set is managed inside the AKiTiO Thunder3 Duo Pro, there is nothing else do be set up on the computer.
2-Lane PCIe to SATA controller
The PCIe to SATA controller makes use of two PCIe lanes. When using Non-RAID and Thunderbolt, this makes it possible for a single SSD to run at full SATA 6Gb/s speeds and deliver transfer rates in read over 500MB/s.
Compatible with Thunderbolt 3 and USB computers
The AKiTiO Thunder3 Duo Pro was designed for both Thunderbolt 3 and USB computers. The device can be connected via Thunderbolt 3 (USB-C) or USB 3.1 Gen 1 (Type-B) interfaces.
Tool-less drive installation
For added convenience and flexibility, the AKiTiO Thunder3 Duo Pro can accommodate both 2.5-inch and 3.5-inch drives. The assembly is completely tool-less, so drives can be easily installed or uninstalled no matter where you are.
Noiseless 0dB operation
For quiet environments, the built-in fan can be turned off completely. The fan switch is accessible from the outside, so the enclosure does not have to be opened. In combination with solid state drives (SSD's), this will result in a completely noiseless storage solution.
The AKiTiO Thunder3 Duo Pro provides users the ability to edit and playback multiple streams of HD and/or 4K content with enough headroom to daisy-chain multiple 4K displays simultaneously.
The transfer speeds for this benchmark were obtained using the AJA System Test tool with 1GB test files at 5k resolution. These results closely reflect the real-world performance but the actual transfer rates can vary depending on the test environment
For the traditional spinning hard disk drives, in this test, the maximum transfer rate for a single drive is around 200 MB/s. This is the reason why only the speeds for a RAID 0 set exceed 200 MB/s and the rest of the results are almost identical.
For the solid state drives, the maximum transfer speed of the USB interface has been reached at around 400 MB/s. A Thunderbolt computer is required in order to take advantage of the speeds those SSD's can reach, even for a single SSD.
The maximum speed of two SATA 6Gb/s SSD's in the AKiTiO Thunder3 Duo Pro is around 700-800 MB/s. For even higher transfer rates, please consider striping two AKiTIO Thunder3 Duo Pro units, using a 4-bay storage solution like the AKiTiO Thunder2 Quad Mini or the AKiTiO Thunder2 Storage-AV, which is designed for two M.2 PCIe SSD's instead.
Frequently asked questions about the Akitio Thunder3 Range and Mac
How about older Thunderbolt and Thunderbolt 2 products with the Thunderbolt 3 to Thunderbolt 2 adapter?
Yes, existing Thunderbolt and Thunderbolt 2 devices from Akitio will work fine on the new MacBook Pro with the bidirectional adapter from Apple or with our own T3T adapter. There might be some models that require a firmware update but testing is currently still ongoing. Once we have concluded all the tests, we will update this page again. For more details about the compatibility of the adapter from Apple, please refer to https://support.apple.com/en-us/HT207266.
How about an older Mac in combination with the Thunderbolt 3 to Thunderbolt 2 adapter?
The bidirectional adapter from Apple can connect Thunderbolt 3 devices to a Mac with a Thunderbolt or Thunderbolt 2 port but it requires macOS Sierra. For more details about the compatibility of the adapter from Apple, please refer to https://support.apple.com/en-us/HT207266. In our tests, we found that with Mac OS 10.10 the adapter does not work at all but with Mac OS 10.11 and macOS 10.12, the adapter appears to work. The devices mentioned above that are currently not compatible with the MacBook Pro 2016 (Thunder3 Duo Pro, Thunder3 PCIe Box, Thunder3 Quad) appear to work OK on a Thunderbolt or Thunderbolt 2 computer. The Node and the PCIe SSD are still not compatible.
How about Boot Camp?
Boot Camp is not part of the Thunderbolt™ compatibility testing and certification process by Apple and Intel. Even if the product has been certified for Windows, this does NOT include systems that are running Windows on a Mac with the help of Boot Camp. For this reason, Akitio does not support Boot Camp. If you still want to use Boot Camp, in our experience, the external storage drives are recognized by the system as long as you connect them before starting up the system. Hot plug is not supported. External GPUs like the AKiTiO Node are not supported at all.
Are you really sure that the Node is not compatible with a Mac computer?
Yes, we can only confirm that the Node is compatible with the Thunderbolt 3 Intel NUC and the Razer laptops. Several other PCs using Windows 10 appear to be compatible upon initial testing but the Node is NOT compatible with the Mac.This also applies to a Mac running Boot Camp and to older Thunderbolt 2 computers. Having said all that, we are aware how dedicated the eGPU community is and who knows, as this statement is published, someone might already have found a way to make it work anyway.
How long do I have to wait for these new Thunderbolt 3 products that are compatible with both PCs and a Macs?
We are currently working to make all of our Thunderbolt 3 products except the Node and the Thunder3 PCIe SSD compatible with Windows and macOS. As this includes a hardware change and the new products have to be re-tested and re-certified to make sure everything is working as expected, it's likely going to take some time. As a rough estimate, we expect the first products to be available at the beginning of the next year (2017).
If I cannot use the Node on my Mac, how can I then use a full-length PCIe card?
We are working on another Thunderbolt 3 PCIe expansion chassis designed for full-length cards, other than external graphics cards, that will work with both Windows and macOS. Please give us a bit of time and we will have the right solution for you.
