The Impact of USB 3.0 On Other Products

Jun. 05, 2021

Let's take a look at wireless USB devices. Currently, more than 6.2 billion products have been shipped using USB 2.0 technology, with 2.1 billion shipped in the last year alone. Among them, a large percentage of the application of wireless USB Technology, it can help users from the complexity of cable connections. The current wireless USB standard has the same data transfer rate as the current wired USB2.0 standard, both at 480Mbps per second. the difference between the two is that wireless USB requires a personal computer or peripheral device equipped with a wireless transceiver rather than a cable connection. In the future, USB 3.0 is compatible with older versions. When USB 3.0 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 USB 1.1 specification for keyboards and mice had transfer speeds of less than 12Mbps, while FireWire locked down audiovisual applications such as video cameras with transfer rates of 100Mbps or more... However, over time, USB has gained widespread adoption, with speeds reaching 480Mbps for the current 2.0 standard. in contrast, FireWire is far less widely used. the USB 3.0 standard is obvious, and it's easy to see that it will overtake FireWire across the board. members of the USB 3.0 camp say that the standard will be able to replace FireWire. And noted that FireWire has lost many industry supporters, such as Sony has switched to USB 2.0 on products such as cameras, Apple is also planning to switch to high-speed USB interface. 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 it can reach speeds of up to 10 Gbps. predictably, the struggle between USB and FireWire will continue. With the early introduction of USB 3.0 devices, the advantage of USB will be further expanded. The coexistence of the two interfaces has existed for a long time, and will do so in the future. But the prospect of a universal interface is clearly more accepted by users.

There is also the hard drive and notebook market that many people do not consider will also be impacted by high-speed USB 3.0 devices. We know that the current maximum transfer speed of hard disk SATA interface is 3Gbs, which is far lower than USB3.0 devices. It could bring two changes. One is the use of USB to connect hard drive products inside notebooks. For notebook products with hard drives or notebook products with only small size and capacity hard drives such as solid state drives, their main hard drive relies on an external USB3.0 interface hard drive. This not only further reduces the size of the notebook and reduces the heat generated by the notebook, but also makes it very easy to upgrade the notebook hard drive.

The emergence of USB 3.0 has not only brought us an increase in the transfer speed of unilateral products, but also promoted the improvement and development of the entire industry.
