The 7 Best Thunderbolt Accessories for Your Mac

Dan Price Updated 05-11-2019

Thunderbolt is a hardware interface used for connecting accessories and peripherals to your computer. The latest iteration of the technology—Thunderbolt 3—uses USB-C connectors, meaning it’s also compatible with some Windows machines.


The interface can transmit data at 40Gbps, support two 4K monitors at 40FPS, supply 100W of power when charging devices, and a whole lot more.

It all sounds great, right? But which Thunderbolt 3 gadgets and devices are worth buying? Here are our top picks for Thunderbolt accessories for your Mac.

1. Samsung X5 Portable SSD

The Samsung X5 Portable SSD is arguably the best external hard drive with a Thunderbolt connection. The NVMe-based device offers read speeds of 2,800MB/s and write speeds of 2,300MB/s. That level of performance is almost five times faster than a SATA interface and more than 20 times faster than a typical external hard drive. As such, the drive is perfect for content creators and other professionals who need to transfer huge files at breakneck speeds.

Three different sizes are available; 500GB, 1TB, and 2TB. For the top model, you can expect to see the price tag hitting four figures. All three models have Dynamic Thermal Guard technology to prevent overheating, and they all have shock-resistant frames that can withstand a two-meter fall. And, importantly, you also have the option to secure all the data on your device with a password and to encrypt it using AES 256-bit standards.

If your primary computer is a laptop rather than a desktop, there are many times when you might need a larger monitor or a second monitor. Of course, there are lots of reasonably priced second monitors out there. However, if you want to really enjoy the benefits of Thunderbolt 3, it’s worth opting for the high-spec LG 27MD5KB-B UltraFine 27″ Monitor.

It offers 5K 5120 x 2880 resolution, a 1200:1 static contrast ratio, a 60Hz refresh rate, 178-degree viewing angles, and 1.07 billion colors. If you work in a creative field in which color display and high resolution are essential requirements of a second monitor, you will struggle to find a better product. The LG Ultrafine Monitor also boasts a built-in webcam, two 5W speakers, and support for picture-in-picture viewing.

Today, many laptops have a significantly reduced number of ports compared to models from a few years ago. If you’re the type of user who still needs to connect several gadgets to your computer at the same time, that’s an issue. The solution is to use a Thunderbolt 3 dock.

They can expand a single Thunderbolt port on your computer into several ports for different purposes. The CalDigit TS3 Plus Thunderbolt 3 Dock, for example, provides 15 different connections through a single laptop connection. It includes ports for USB-A, USB-C, digital optical audio, and gigabit ethernet.

If you’re a gamer, one of the best Thunderbolt 3 accessories worth buying is an external GPU chassis.

An external GPU chassis also helps to future-proof your machine; you’ll always be able to swap and upgrade the graphics card.


One model you should consider is the Razer Core X. It can take three full-size PCIe desktop graphic cards. The fact it supports full-size cards means you can use top-of-the-range models like the NVIDIA GeForce, NVIDIA Quadro, or AMD Radeon. Furthermore, most alternative external GPUs on the market can only handle either one or two cards, giving the Core X another advantage. The chassis has a massive 650W power supply with 100W power delivery. Graphics cards are not included, though.

5. MOKiN Gigabit Ethernet Adaptor Hub

Thunderbolt 3 supports ethernet networks. It means that aside from being able to connect to a regular ethernet network, you could also utilize the Thunderbolt interface to create a high-speed peer-to-peer network. Indeed, it is the fastest way to transfer data directly between two machines.

To either connect to a standard network or to join two machines together, you will need an ethernet adaptor. One of the best models available is the MOKiN Gigabit Ethernet Adaptor Hub. Not only does it allow you to connect an ethernet cable, but it also has three regular USB-C ports, thus allowing you to connect additional peripherals.


6. Plugable Thunderbolt 3 Cable

It’s all well and good having an impressive array of the best Thunderbolt accessories in your home or office, but they are not much good if you can’t connect any of them to each other! As such, it’s worth investing in a couple of Thunderbolt 3 cables and keeping them handy; you never know when they might prove to be useful.

As with most types of computer cables, some cables are dirt cheap and not worth your time. Others are made from premium material and are way beyond the needs of most users. For a solid balance, consider the Plugable Thunderbolt 3 Cable. It comes in three different lengths: 0.5 meters, 0.8 meters, and two meters. The two-meter cable only supports 20Gpbs; the 0.5-meter and 0.8-meter cables provide 40Gbps.

    Hmm, i'm looking for a Ethernet or Firewire adaptor with dual thunderbolt ports / two ports - so it could be used within a thunderbolt chain.

    any suggestions?

    I just found a few docking stations which are overkill for my needs (don't need the other ports / interfaces of such devices.

    Many thanks for your help.

    The Kanex adapter wouldn't keep a USB hard drive mounted for me in Yosemite. Randomly would just disappear. You get what you pay for. The new Belkin thunderbolt 2 dock is amazing and works spectacularly though.
