Let’s take a look at wireless USB devices. At present, the shipment volume of products using USB 2.0 technology has exceeded 6.2 billion, and the shipment volume last year alone reached 2.1 billion. Among them, the application of wireless USB Technology occupies a large proportion, and it can help users free themselves from the complicated cable connection. The data transfer rate of the current wireless USB standard is the same as the current wired USB2.0 standard, both are 480Mbps per second. The difference between the two is that wireless USB requires a personal computer or peripheral device to be equipped with a wireless transceiver instead of a cable connection . In the future, USB 3.0 is compatible with the old version. When USB3.0 technology matures, our wireless USB technology will also be greatly improved.
Let's look at the impact on Firewire. At the beginning of the USB standard in 1990, the USB1.1 specification for keyboards and mice had a transmission speed of less than 12Mbps, while Firewire locked audio-visual applications such as camcorders with a transmission rate of 100Mbps and above. . However, with the passage of time, USB has been widely used, and the speed has reached the current 2.0 standard of 480Mbps. In comparison, the application of Firewire is far less extensive. The USB3.0 standard is obvious and it is easy to see that it will fully surpass FirewireUSB3.0 camp members said that the standard will be able to replace Firewire. And pointed out that Firewire has lost many industry supporters, such as Sony has switched to USB 2.0 in products such as cameras, and Apple is also planning to switch to high-speed USB interfaces. However, the new Firewire specification is also under development. It will continue to use the same cables and connectors that define the current 1394b standard, but its speed can reach up to 10Gbps. It is foreseeable that the struggle between USB and Firewire will continue. With the advance launch of USB3.0 devices, the advantages of USB will be further expanded. The coexistence of the two interfaces has existed for a long time, and it will be the same in the future. But the prospect of universal interfaces is obviously more accepted by users.
USB 2.0
There are also hard disk and notebook markets that many people have not considered will be impacted by high-speed USB3.0 devices. We know that the highest transmission speed of the current hard disk SATA interface is 3Gbs, which is much lower than USB3.0 devices. It may bring two changes. One is the use of USB to connect hard disk products inside the notebook. For notebook products with hard disks or only with small-volume, small-capacity hard disks such as solid state hard disks, the main hard disks rely on external USB 3.0 interface hard disks. This not only can further reduce the size of the notebook and reduce the heat generation of the notebook, but also can upgrade the notebook hard disk very conveniently.
The advent of USB3.0 has not only brought us an increase in the transmission speed of unilateral products, but also contributed to the improvement and development of the entire industry.
