Since 2020, WFH (Working from Home) has become a popular term and changed our method of working. However, a lot of people find that the transmission speed of their computer is not meeting their needs. Here is a story. Jerry Lin, who is engaged in video shooting and editing in a local small business, is facing this difficulty. During the epidemic, he works from home, using a PC to edit videos filmed by a camera and upload them on the Internet. Nevertheless, the video files are often at 10GB or 15GB. Sending an edited video from a computer to a memory card always takes 5 minutes. Transferring a large number of files may take half a day, which is a waste of time.

Back in 1994, Intel reached a consensus with computer industry giants such as Microsoft and jointly launched the first USB transmission standard and the USB Standardization Organization (USB-IF) was also born. There was a big demand, and the USB specification has also brought a new milestone in 2021. That is, USB4 evolved from 1.0, 2.0, and 3.2. The complete name of USB is "Universal Serial Bus ". When it was first launched, the original transmission speed was only 1.5MB/s, but USB4 has a transmission speed of up to 40GB/s, which is 27000 times faster than the first generation.


Moreover, USB4 is more powerful than our imagination. In the future, except a maximum transmission speed of 40GB per second, when a USB4 cable assembly is connected to a screen, it can power the screen and transmit 8K videos. An independent power cable can be saved. When your laptop is connected to a screen, this cable (USB4) can also charge your laptop and transmit data at the same time. The work of charging power will be taken by USB4 cable – NO NEED MORE POWER CABLE!


With the new generation of USB, Jerry Lin works from home more easily. In a second, a video file is completely transferred where he wants. It does not take 5 minutes just to send or upload a file, saving more time and increase work productivity at the same time. After filming, a camera battery is dying. No worries, USB4 can charge it!
