If your computer has a Thunderbolt 3 interface and you need a high-speed external disk to complete some data-intensive projects, Thunderbolt external hard drives, especially Thunderbolt 3 external hard drives, are your choices. Due to the high transfer rate, the Thunderbolt 3 interface is usually mounted on SSDs to meet the demand for high-speed external disks. Thunderbolt 3 is currently the fastest interface in external storage devices. Read More Best Thunderbolt External Hard DrivesĪfter learning about USB-Type-C and Thunderbolt 3, you may want to know about Thunderbolt 3 hard drives. In addition, the Thunderbolt 3 protocol is compatible with USB 2.0, 3.0, and 3.1. It uses Thunderbolt 3 protocol, which must integrate PCI-E data transmission technology and DP technology, but optionally integrate USD PD. Only a few full-featured USB interfaces can integrate USB 3.0, DP, and USB PD to realize data transmission, video transmission, and fast charge.Īs for Thunderbolt 3 interface, it is the top-level presentation of the USB Type-C interface. Some advanced USB interfaces may integrate USB 3.0 and DP (Display Port) to achieve both data and video transmission. With this protocol, you can connect peripheral displays via corresponding adapters to output video and audio, or you can connect external discrete graphics cards to expand graphics performance.Īt the same time, you have to face the fact that most of USB interfaces mounted on devices can only transfer data and use USB 3.0 protocol (not to mention USB 3.1 and USB 3.2). With this protocol, you can use the USB-Type-C to charge your phone and computer fast.ĭisplay Port Protocol: It is a digital video transmission protocol that can transmit audio and video simultaneously. The power delivered can reach up to 100W. It can increase power transmission through USB cables and connectors to expand the power supply capability of the USB cable bus. USB PD (Power Delivery) Protocol: It is one of the current mainstream fast charging protocols. In addition, these protocols also partly determine how fast your external hard drive can be. With these data transmission protocols, the USB Type-C can transfer data. The USB Type-C port can accommodate the following protocols:ĭata Transmission Protocols: USB 2.0 (480Mbps), USB 3.0 (5Gbps), USB 3.1 (10Gbps), USB 3.2 (20Gbps), and Thunderbolt 3 (40Gbps). The more protocols it accommodates, the more functions it can implement. USB Type-C port can accommodate multiple protocols.

Since the USB Type-C specification was released in 2014, many new 3C devices such as Android mobile devices, laptops, desktops, and even game consoles have begun to use this connection port. Therefore, people usually compare it with the USB interface.ĭo you really know USB-Type-C and Thunderbolt 3? Thunderbolt interface is usually used as an interface for connecting external devices. Tip: Thunderbolt 3 also has three versions: DP (Double Port) version uses a PCIe 3.0 ×4 link to provide 2 interfaces SP (Single Port) version uses a PCIe 3.0 ×4 link to provide 1 interface and LP (Low Power) version only provides 1 PCIe 3.0 ×2 interface. In this post, I will mainly focus on Thunderbolt 3, because Thunderbolt 1 and 2 are not popular due to the following reason: their physical ports are Apple Mini DPs, which cannot be used in other electronic devices therefore, not many manufacturers support them. Therefore, Thunderbolt 3 is incompatible with Thunderbolt 1 and 2.
Thunderbolt 1 and 2 are integrated with Mini DisplayPort (a physical port), while Thunderbolt 3 is integrated with USB Type-C (a physical port). So far, the Thunderbolt interface has developed to the third generation: Thunderbolt 3. Therefore, it can transmit data and video signals at the same time. Thunderbolt is a data transmission protocol combining PCI Express data transmission technology and DisplayPort display technology. Introduction to Thunderbolt Hard Drive and Thunderbolt InterfaceĪs the name implies, a Thunderbolt hard drive is a hard drive with a Thunderbolt interface, which is a technology developed by Intel in collaboration with Apple.
