Thunderbolt is a fast and versatile connectivity standard that links computers and peripherals at ultra-high data transfer speeds. Thunderbolt supports data, video and audio over a single cable and allows multiple devices to be daisy chained. Thunderbolt 3 and the newer Thunderbolt 4 use the USB-C connector and offer data transfer speeds of up to 40 Gbps, making them excellent choices for handling high-capacity devices such as external hard drives, displays and 4K video. Thunderbolt also provides power and device management on a single cable, reducing cable clutter and making connecting devices faster and more convenient. Thunderbolt is particularly popular in professional and creative industries where fast data transfer and high bandwidth are required.
