Best Overall: Akitio Thunder 2 Dock

Compact with sharp looks, the Akitio Thunder2 dock offers a terrific way to connect two Thunderbolt 2 ports. Capable of lightning fast speeds at 20Gbs a port, the Thunder2 dock can handle up to two 4K monitors and displays at a time without blinking an eye. The hardware looks like a hard drive that offers dock ports on three of its four sides. Unfortunately, that means your cables aren’t always likely to be hidden from view but that’s a tradeoff you can make if you aren’t connecting and disconnecting devices with great frequency. Beyond Thunderbolt 2, the Akitio adds dual eSATA ports, a FireWire 800 port and dual USB 3.0 ports that can also charge your portable devices. Geared for Apple-specific machines, what the Akitio lacks in audio connectors or HDMI connectivity, it more than makes up for with speed and good looks.

Runner up, Best Overall: CalDigit Thunderbolt Station 3 Dock

One small drawback to note, aside from the price is that this dock is not compatible with MacBooks that use retina displays.

Best Splurge: Elgato Thunderbolt 3

Elgato is one of the best-known Apple accessory manufacturers available today and its Thunderbolt 3 dock continues that streak. The Thunderbolt 3 dock supports dual 4K monitors or one 5K monitor with a single connection while powering data transfer speeds up to 40Gbs. Plugging directly into the MacBook, specifically Apple’s 2016 and later models, it offers dual USB-C ports, which at 85 watts of power, can utilize pass-through to charge your MacBook Pro as well the rest of Apple’s portable devices, including the iPhone and iPad. Beyond Thunderbolt 3, the Elgato is supported by three USB 3.0 ports, an amplified stereo audio port for a no-compromise audio experience, as well as a Gigabit Ethernet port for faster overall performance than Wi-Fi. Non-Apple users will find the Elgato works well with Windows machines (although the pass-through charging is designed solely with Apple computers in mind).

Best Speed: Amavision Thunderbolt Dock

What to Look for in Thunderbolt 3 and 2 Docks

Thunderbolt 2 vs. 3 - What kind of ports does your laptop have? If you’re working on a late 2016 MacBook Pro or newer, you’ll need a Thunderbolt 3 (or USB-C) dock. If your machine is an earlier model, then you should pick up a Thunderbolt 2 dock.

Windows vs. Mac - While the term “Thunderbolt” immediately brings to mind Macs, many of these docks are compatible with Windows machines as well. If you need a dock that works with both Mac and Windows, then you should take that into account. If you’re looking for just a Windows dock, though, you may want to look at a USB 3.0 model instead of a Thunderbolt.

Ports and size - Do you need to be able to stick your dock in a bag and travel with it? If so, you’ll likely be looking for more of a dongle than what is traditionally thought of as a dock. These are powerful little docks, but they have a limited number of ports. If your dock will remain at a desk, you may want to look at a larger model that will give you options for dual monitors, an Ethernet port, an SD card slot, and more. However, these are often more pricey, so it’s important to balance what you need with the cost.
