CalDigitThunderbolt 4 Element Hub - 4X USB4 Ports, USB 3.2 Gen2 10Gb/s, Single 8K or Dual 4K Displays, 60W Charging, 0.8m Cable

The reversible design is a great touch that makes this dock a standout for a clean desktop device. Well thought out specifications and choices to achieve a vision. Works well with a Dell Precision 5380 and Asus Zephyrus G16 2025 both with an Intel Thunderbolt 4 controller, as well as an Asus G14 2024 with an AMD processor and USB4. All devices were able to charge and daisy chain USB-C adapters with displayport passthrough. Data transfers have been a breeze with the TB4/USB4 datalink easily saturating the USB 3.2 Gen2x1 10Gbps controller of my external storage.

I upgraded a USB 3.0 hub to this excellent unit. I love that full power is available on all ports for charging and that it supports my 4K display, plus another 4K display if I get one. Now I am able to plug a single cable into my Surface Pro 7 for power, video, and peripherals, and I can leave the surface charger in my backpack. Other hubs have ports with limited functionality -- slower speeds, less power, and overall power limits that can reduce power on individual ports when loaded. This hub has full power and speed on all ports. It isn't cheap, but it's a good example of "you get what you pay for." I expect it will serve another generation or three of laptops after my current one, providing lasting value. For those needing more ports, check out Caldigit's Thunderbolt Station 4.

If you need more ports, the Caldigit Express Thunderbolt 4 hub is a very good solution. Since it has its own power supply, it also solves a potential issue with too many peripherals attached to a Mac Studio’s ports causing intermittent disconnects. I had this problem with an external NVME SSD enclosure, and adding this hub solved the problem. My setup successfully recovered from two power outages, powering back up and reconnecting to all my monitors and peripherals. Note, my setup also runs on a UPS to ensure proper shutdown and restart of my computer.

I needed a four port SSD dock I could use for updating my external SSD backup drives. I had been using four TRIM compatible enclosures connected to the four USB ports on the left side of my laptop (see the last photo below) but it was a pain (guess where) to set up and tear down every time I updated my backups and ate up too much precious space on top of my desk.I could find only two SSD only docks but they were too bulky and would be too slow since all four or five ports ran off a single USB 3.0 connection (up to 5.0Gbps) so I built my own dock from four cut down 2.5" TRIM compatible enclosures and connected them to the four USB Type a ports on the Element hub. I run the hub off a Thunderbolt 3 port (20Gbps) on the laptop (that provides up to 5 or 6Gbps, the max for SATA, per drive, depending on how many drives are being written to at the time.The dock/hub stay setting on top of my desk. The enormous PSU is Velcroed to the side of my desk to keep it out of sight and out of the way but still easy to access if I need to.Redneck as it sounds, it works great and doesn't look too bad. Not only does it run faster than my old setup, it takes up less space, is less hassle to use, and I still have three USB ports available on the left side of my laptop. The hub itself gets a bit warm when in use, but nowhere hot enough I can't comfortably hold my hand on it. Curiously, the PSU stays cool. I have the PSU power cord plugged into a switched outlet cube located where I can easily reach it from my desk so I can turn off the dock/hub when not in use.TRIM works through the hub. I'm using Linux Mint 19.3 Cinnamon 64-bit.Since the four USB type A ports will max out Thunderbolt three, I do not plan on using the other three ports on the other side. They are too inconvenient to get to anyway.For some odd reason, the dock/hub will not work on the Thunderbolt ports on the other two laptops I have built on the same Clevo chassis as my daily driver. I suspect there may be a driver issue there. Those laptops are just backups and for travel so I'm not losing sleep over it.

The CalDigit Thunderbolt 4 Element Hub is a well-built and reliable hub. I’ve been using it with my Mac Mini M4 Pro, and it performs consistently — excellent data transfer speeds, stable connectivity, and clean power delivery.However, I wish it had more Thunderbolt 4 ports instead of four USB 3.2 Gen 2 Type-A ports. Having more 40Gb/s TB4 ports would have made it perfect for high-end setups with multiple external drives or displays.Overall, it’s a great hub for most users, but power users might want more Thunderbolt flexibility.

This is the worst item I have bought. I have tried everything to get it to connect to my Thunderbolt enabled ASUS Zenbook but the computer does not recognize it. Trying to connect anything through this product doesn't connect. It is worthless and too late to return.After I connected with CalDigit about my problem, I realized I had set the hub up wrong. Once I corrected my mistake, it works great.
