Why do you need a Thunderbolt 3 SD Card Reader?

SD cards have fast gained popularity as one of the best storage and data transfer media due to their portability and a secure mode of data transfer.

The media industry has vastly used SD cards as its primary mode of storage due to its portability. Most, if not all, cameras use them as their sole mode of storage.

Apart from the media industry, their use is slowly becoming familiar to a significant number of users. Most of these users have decided to use them as a means of data transfer because of its convenience.

With more users embracing SD cards as their mode of data transfer and backup, the technology has advanced to new standards such as the SDHC (Secure Digital High Capacity), SDXC (Secure Digital Extended Capacity) which support the SD 4.0 UHS-I (Ultra-High Speed) and UHS-II speeds.

This advancement has created the need for card readers that can conveniently read and write data at high speeds, hence the invention of the Thunderbolt 3 SD Card Readers.

Thunderbolt 3 is a connection port that supports the fastest data transfer on a single cable. It offers multipurpose connection to data devices, displays, and docks with speeds of up to 40 GB/s. The Thunderbolt 3 port is similar to the USB Type-C ports; however, not all USB-C ports are Thunderbolt 3 Compatible.

If you have recently acquired a MAC, PC, a laptop, or even a High-End phone with OTG support, then there is a high chance your device is Thunderbolt 3 compatible.

If your device does not automatically support Thunderbolt 3, you can still enjoy the fantastic speeds by purchasing a Thunderbolt 3 PCIe card to enable your motherboard to support Thunderbolt 3. Please check out with your manufacturer to establish if your motherboard supports Thunderbolt 3 before purchasing the Thunderbolt 3 PCIe card.
