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.

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.
