As for its unique selling point, it comes in the shape of an M2 slot found underneath the device, that can be removed by taking out two screws.

What experts didn't like

Dual display setup suffers in performance when trying to use the full 4K resolution.
- BestReviews
Performance is subpar on the two USB 3.1 G1 Type-C ports. I was able to reach 359 MB/s read and 325 MB/s write in testing and while that is average for most solutions like these, StarTech can do better. Moving on to the Gigabit Ethernet, we once again found subpar performance for the Intel i210 Gbe controller reaching a peak of 500 Mbps in testing.

There’s nothing revolutionary about the design of this docking station; Startech stuck with the traditional elongated black metal brick design. It only has 11 connectors and ports; Caldigit has 15 in comparison.

An Overview On Thunderbolt Docking Stations

Workers are more mobile than ever. Whether you report to an office 40 hours a week or not, chances are you have a need to take your computer with you when you leave. Docking stations have long been a convenient way for workers to enjoy the mobility of a laptop while still having access to the screen, mouse and keyboard they prefer when they’re seated at a desk.

With a Thunderbolt, you get the benefits of speedy technology to charge compatible devices quickly. But as technology and parenting blogger Molly Thornberg explains, Thunderbolt docking stations come in a variety of options.

“Each Thunderbolt Docking Station has its own unique set of ports and features,” says Thornberg, the brains behind the Digital Mom Blog. “Research before buying a docking station to ensure that all of your needs are covered. Some commonly found ports and features include: additional Thunderbolt ports, USB-A ports, USB-C ports, computer charging, displays, a Gigabit Ethernet port, an SD reader and an audio port.”

But there are several things to consider before you choose a docking station. The first is compatibility with the devices you use every day. With some docking stations, you can plug in multiple electronic items, which means you can charge your mobile devices while using your laptop. You’ll need to check to make sure your docking station has ports that will work with the cables that connect to your devices.

When it comes to ports, advances in technology have made things a little complicated. You’ll see both USB-A and USB-C ports advertised, as well as the rating of USB 3 and USB 2. These are standards applied to data transfers, and both USB-C and USB 3 are newer. You’ll recognize USB-C by its smaller port size, as seen on newer computers and mobile devices. USB-A is the type you’ve seen for years, with a larger port on both the devices and the cables you plug into them.

When looking at ports, consider all the things you’ll need to plug in. If you prefer to have two monitors, make sure your docking station will support that and check how much the video quality will degrade when the signal is split between two monitors. Also keep in mind whether the ports are in the back or front of the docking station, as that will influence how far your cable will have to reach.

There are some cosmetic considerations, as well. You probably have limited space on your desk, so a docking station that sits vertically rather than horizontally can provide some relief. You should also take a look at the basic design of your docking station, as it will become an important part of your office aesthetic.

For many people, it may not matter, but for photographers and videographers, an SD card reader is essential. These professionals often need to quickly offload photos or videos to a memory card at the end of each day. If they’re in a rush, the process of transferring the data can be cumbersome. With a good SD card reader, you can get the high-speed transfer you need, allowing you to spend less time waiting and more time working.

The Thunderbolt Docking Station Buying Guide

  • You likely already know what devices you want to dock. If you need your docking station to power a MacBook Pro or PC, you’ll want a unit with plenty of power. The CalDigit TS3 Plus Thunderbolt Dock and gofanco Mini DisplayPort are compatible with the Apple MacBook Pro, although the gofanco Mini DisplayPort won’t work with 2015 MacBooks.
  • The CalDigit TS3 Plus Thunderbolt Dock provides 85 watts of power, which is plenty to charge a 15-inch MacBook Pro at full speed.
  • An 85-watt docking station will also provide enough power for you to set up a compatible host to serve as a charging station.
  • For compatibility, you’ll need to make sure your chosen Thunderbolt will work with the devices you have.

“Using just one Thunderbolt port on your computer, a docking station expands that to however many ports your particular docking station offers,” Thornberg says. “These additional ports come in handy when your computer or laptop does not have the ports you need built-in, if you are out of ports or want additional functionality.”

  • The CalDigit TS3 Plus Thunderbolt Dock can connect to any Windows or Apple device that has a Thunderbolt 3 port on board. Thunderbolt 3 was released in 2015 and designed to provide fast connections to docks.
  • The CalDigit TS3 Plus Thunderbolt Dock promises to offer the most ports, and it doesn’t disappoint. You’ll get 5 USB-A ports, ideal for plugging in hard drives, mice and keyboards. You’ll also get two USB-C ports for devices that support that. The gofanco Mini DisplayPort has two USB-A ports, while other models have two USB-A ports and one USB-C port.
  • If you’re limited on desk space, look for a docking station with a smaller footprint. The CalDigit TS3 Plus Thunderbolt Dock stands upright to minimize the real estate they consume.
  • Those who need to transport the dock from home to work and back again may want to look for a lightweight model. The gofanco Mini DisplayPort is the lightest at only 6.4 ounces, but the CalDigit TS3 Plus Thunderbolt Dock measures around one pound. Other models can weigh as much as 3.25 pounds, making them best for those who plan to keep the docking station in one place for the duration.
  • Whether you’re regularly moving your docking station or not, you’ll likely want a unit that’s built to last. The CalDigit TS3 Plus Thunderbolt Dock has a strong aluminum case that should hold up against anything that might fall on it.
  • As you’re looking at ports, pay close attention to which docking stations have easy-to-access connections on the front of the device. Since your docking station will most likely be on your desk, not having to reach around to plug in those often-used items will come in handy. Your keyboard and mouse may be fine to stay plugged in permanently, for instance, but you’ll be connecting and disconnecting items like your laptop and headphones on a daily basis.
  • Some consumers use mobile storage solutions regularly. If you’re a professional photographer or videographer, for instance, you may need to quickly download your footage for safekeeping when you return home at the end of each day’s work. The CalDigit TS3 Plus Thunderbolt Dock has an Ultra High Speed II (UHS-II) SD card reader to transfer your data at lightning-fast speeds.
  • If you prefer to use multiple monitors, consider the CalDigit TS3 Plus Thunderbolt Dock. The CalDigit TS3 Plus Thunderbolt Dock can handle up to two monitors along with the usual peripherals. However, if you’re going for the highest resolution possible, you may notice resolution starts to degrade once you’ve split the connection between multiple monitors.
  • For those on a budget, the gofanco Mini DisplayPort will be the most affordable choice, but beyond that extremely low cost, you’ll find most other options are similarly priced.
  • Resolution can be an important feature, especially if you’re a gamer or you watch video on your monitor. The CalDigit TS3 Plus Thunderbolt Dock lets you connect two 4K monitors or one 5K monitor. Other models give you 4K resolution on up to two monitors, while the gofanco Mini DisplayPort gives you 1080p resolution.
  • The overall design of your docking station may come into play, particularly since it will become a prominent part of your office environment. The CalDigit TS3 Plus Thunderbolt Dock looks similar to a router, but you’ll find the gofanco Mini DisplayPort has a much lower profile, coming in the form of a small box.
