Belkin today announced that its Thunderbolt 3 Express Dock HD is available for purchase on the Belkin website, in Apple retail stores, and on Apple.com.

Priced at $349, Belkin's Thunderbolt 3 dock is one of the more expensive dock options available on the market, but for that price, it features an aluminum body, a stylish tapered design, 85 watts of power delivery for charging Apple's 15-inch MacBook Pro, and a range of ports.


The dock includes Two Thunderbolt 3 USB-C ports, three USB-A ports, one DisplayPort, a Gigabit Ethernet port, an Audio In/Out port, and a second Audio Out port. Up to five Thunderbolt devices can be daisy-chained from the dock and it offers a 170W power adapter to supply power to attached peripherals while also charging a MacBook Pro.


Belkin's dock is able to support a single 5K monitor or two 4K monitors, and it supports data transfer speeds of up to 40Gb/s.

We went hands-on with the Belkin Thunderbolt 3 Express Dock HD last week, so make sure to check out our review for more details and to see how it measures up to other Thunderbolt 3 docks.

Does plugging it into your computer cause the dock to lose one one of the Thunderbolt 3/USB-C ports? Therefore, this dock would only actually come with one useable Thunderbolt 3 port?

Yes. All the dock manufacturers claim "Two Thunderbolt 3 ports" which is technically true but practically misleading.

Thunderbolt is a "daisy chain" architecture - each port on the computer can support a chain of TB devices but you can't trivially* have "hubs" that share one TB input between many outputs. USB is a "star" architecture that can have one-to-many hubs.

A hybrid USB3/TB3 network with a backbone daisy-chain of 20-40 Gbps TB boxes each driving multiple USB3 peripherals is actually a sensible solution - since USB peripherals are cheaper and most individual devices don't need full TB3 bandwidth.

If you do have a mega SSD/pro-audio/video device that needs TB bandwidth, its more sensible to have it directly hooked to the Mac.

Also remember that dual 4k@60Hz displays - or a single 5k - will eat over half the bandwidth of a single TB3 port so, although there's plenty left for your ethernet and legacy USB devices, if you have any TB3 devices that really use the interface you really don't want to plug them into the same dock as your displays.


* You'd need a second thunderbolt controller in the dock - assuming that's even technically possible.
