Node Duo
Thunderbolt 3 PCIe Expansion Chassis

Thunderbolt 3 / PCIe / DisplayPort
The Ultimate Plug and Play Expansion Kit
The Node Duo, with space enough for two half-length PCIe cards, is the ultimate plug and play expansion kit for Thunderbolt 3 computers (e.g. laptop computers) where installing an internal expansion card is not an option and for systems where there is not enough space for more PCIe cards. The Thunderbolt 3 (USB-C) connection not only makes adding an external PCIe card easy but it also allows you to take the device with you to use on location and move it from one system to another.
Supports two PCIe Gen3 x2 cards
The two PCIe slots accept half-length, full-height, double-width cards and provide 25W of power each. If only one PCIe card is installed and the power delivery function is not used, the PCIe slot can provide up to 75W of power.
Upgradeable power supply
For PCIe cards that require more power, this device can be modified accordingly. For more power, the included 150W power adapter can be replaced with a bigger power adapter (min 230W), making it possible to provide up to 75W of power to each slot. For even more power, the breakaway-tab on the back panel can be removed to create an opening, which can then be used to run a cable from an additional PSU like AKiTiO's 500W SFX PSU directly to the PCIe card (e.g. 6+2-pin PCIe power cable).
Power Delivery (60W)
The reversible USB Type-C (USB-C) connector enhances ease of use for connecting devices with a focus on minimizing user confusion for plug and cable orientation. The Node Duo also supports power delivery (PD) over USB-C, providing up to 3A at 5V, 9V, 15V, 20V with a maximum of 60W of power to compatible laptops like the MacBook Pro (late 2016) that support charging through the USB-C cable or for devices like the iPad Pro. This allows you to recharge your battery even though the laptop is not plugged into any other power source.
Thunderbolt™ 3
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 to bus-powered devices.

The Node Duo has two Thunderbolt 3 ports. The second port 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.
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.

Rating: 5/5 Really works, unique and great product. June 7, 2021 The best solution for a volume thunderbolt storage. Akitio thunders supports dual pci to 8x nvme m1. Even though there will be less PCI lanes per drive, if you populate both slots it will give you full performance for 16 m1 drives for a whopping 128GB SSD if you get 16x 8GB m1 drives. The only product to do so. Please do not discontinue and keep supporting! Thanks for cool product.

I would recommend this item to a friend!

Rating: 5/5 I'm in LOVE! June 4, 2021 I'm coming from a failed Thunderbolt 1/2 chassis from another manufacturer (no need to name names) that was housing my SUPER old SSL MADIXtreme and UAD-2 Quad PCIe cards. and by "failed", I mean it was working and has served me (and my fellow studio nerd that gifted it to me) very well. but, it died. no power, no warning, no nothing. I was going to replace it with same box; used it I could find one since I'm trying to save money. no dice. not wanting to pay full retail, I had to open my options. and that led me to the Duo. as I'm a 2018 Mac Mini use, I liked the styling right away (Space Gray Cheese Grater, anyone??) and it was on sale. win. only potential downside was while the compatibility chart said that my SSL card was supported, unfortunately, my UAD Quad card had not been tested and was not listed as a supported device, so there was no guarantee it would work (there is mention on the compatibility chart that your device not being listed doesn't mean it's NOT supported, just untested). I took the chance and leaped anyhow. and I'm glad I did. took a week to get to me, but when it got here I keep getting more and more impressed by the presentation and AMAZING packaging. once open, the chassis is even more beautiful in person!! the unit is approx. 12 lbs., so it feels solid and sturdy...obvious thought went into the design and construction. ZERO tools needed as all as the screws to open the box and card slots all use finger screws, so it was super easy to install the cards. and...both cards worked and were recognized as soon as I popped them in. another score! plenty of space for both cards and they'll be sure to be adequately cooled by the much larger fan than I'm used to in my other box, that is still quiet enough to not be annoying. a SUPER robust external power supply and they even included a FREE 2m Thunderbolt 3 cable! truly the gift that keeps on giving! $330 (including tax/shipping)! of course this is only Day 2 with the Duo, but as the headline says...I'm absolutely in love with this unit so far! **FYI: please be aware the box is fairly large. I had to do some moving things around to get it to fit the space nicely. small (no pun intended) price to pay for what you get. YMMV. still, if you have a need

I would recommend this item to a friend!
