From 1998 to 2000, many companies claimed to be the first USB flash drive. Including China's lucent technologies, Israel m-systems, Singapore Trek. But it was China's lucent that really patented the basic invention. In July 2002, the company was granted the official authorization of the state intellectual property office for the "flash electronic external storage method for data processing system and its device" (patent no. : ZL 99117225.6). The patent fills the gap in China's 20-year patents for computer storage. The acquisition of the patent caused a great shock to the entire storage community. Including Israel's m-systems, it immediately submitted an ineffective review to the state intellectual property office, which once became a global flashpoint in the global flash drive. But on December 7, 2004, the company was granted the patent for a flash disk based on the official authorization of the U.S. Patent Office, US6829672. The acquisition of the patent ended the fight. China's lucent is the world's first inventor.

Most flash drives support the USB2.0 standard; However, due to the limitations of NAND flash technology, their speed of reading and writing is still not up to the maximum speed of 480Mbit/s supported by the standard. The fastest flash drive currently USES four or more channels, but it's still a bit worse than the hard disk or the maximum transmission rate that USB2.0 can offer. By comparison, USB3.0 is faster and can beat common mechanical hard drives, with the highest transmission rate currently at about 220MB/s, while the average minimum file transfer speed is about 10MB/s. The older version of the 12Mbit/s device has a transmission rate of about 1MB/s.
