When Type-C Data Cable is actually transmitting large-capacity files, the stability of the transmission speed is affected by a combination of factors.
First, the transmission standard supported by the data cable itself is crucial. If it is a Type-C Data Cable that complies with the USB 3.1 Gen2 and above standards, it can theoretically provide a higher and more stable transmission speed, up to 10Gbps or even higher. Under this high-speed standard, there is a better basic guarantee when transmitting large-capacity files such as Blu-ray movies (usually tens of GB in size) or large game installation packages. However, if the data cable is only USB 2.0 standard, its theoretical maximum speed is only 480Mbps. When transmitting large-capacity files, the speed is not only slow, but also more susceptible to interference from other factors and unstable.
Secondly, the connected devices also have a great impact on the stability of the transmission speed. If both ends of the connection (such as computers and mobile hard drives) support high-speed data transmission protocols, and their internal storage read and write speeds can keep up with the transmission speed of the data cable, then it is more likely to remain stable during the transmission process. For example, when the computer's solid-state drive has a fast read and write speed, and the mobile hard drive is also a high-performance product, the Type-C Data Cable can transfer large-capacity files between the two more stably. However, if the storage read and write speed of one end device is slow, like an old mechanical hard disk, its read and write speed bottleneck will cause the transmission speed to fluctuate, and even if the data cable itself supports high-speed transmission, it cannot give full play to its advantages.
In addition, external environmental factors cannot be ignored. If there is a strong electromagnetic interference source around the data cable, such as other high-power electronic devices or a large number of wires in operation, it may affect the transmission of data signals and cause unstable transmission speed. At the same time, the quality of the data cable also plays a key role. High-quality data cables have good conductivity and strong anti-interference ability of the core material, and good contact at the interface, which can effectively reduce signal attenuation and loss, thereby ensuring the stability of transmission speed. Poor-quality data cables may experience a decrease in speed or even interruption when transmitting large-capacity files due to problems such as poor core material and loose interface.
