Sharing of data is an essential task be it for individuals, organizations, or systems. Thunderbolt Bridge is an efficient technology that promotes data sharing with high efficiency.

What is Thunderbolt Bridge?

Thunderbolt Bridge is a useful feature that is used for data transfer between Mac and other devices via a Thunderbolt port. Compared to other mediums like an ordinary USB cable or ethernet or WiFi, Thunderbolt bridge performs at an exceptionally faster rate to transfer data (Up to 8 Gbps).

It is a highly recommended method when it comes to sharing large-sized files that require a lot of bandwidth.

Thunderbolt Bridge basically acts as a middleman between two devices that are Thunderbolt-enabled and create a direct connection that allows users to transfer data with high speed and performance.

With the help of this technology, you can easily transfer data between two Macs or from your Mac to another Thunderbolt-enabled device.

And here comes the best part about this intuitive technology. Thunderbolt Bridge is bi-directional. So, this simply means you can send and receive data on both devices at the same time. It bypasses the need for a computer and enables users to transfer data seamlessly.
