Do you understand it? What you don't know about U disk

- Nov 10, 2018 -

The history of the U disk is not long. It first appeared in 1999. In order to solve the unsafe and low capacity of the floppy disk drive, the mobile hard disk was born with the disadvantage of being shock-resistant and difficult to carry. It is this unremarkable little thing that has changed people's concept of mobile storage. In a few years, it has been easy to dismount the veteran "soft drive" that has served us for 10 years and become the king of the new generation of mobile storage.


    The USB flash drive can be used to store any data files and to easily exchange files between computers. The USB flash drive uses Flash Memory and Universal Serial Bus (USB) interface, which is lightweight, exquisite, portable, large, safe and reliable. The USB flash drive can be plugged directly into the USB port of the computer or connected to the computer via a USB adapter cable.


    In terms of capacity, the capacity of the U disk is optional from 16M to 2GB, breaking through the limitations of the floppy drive 1.44M. From the point of view of read and write speed, the U disk adopts the USB interface standard, and the read/write speed is greatly improved compared with the floppy disk. In terms of stability, the U disk does not have a mechanical reading and writing device, which avoids damage caused by the mobile hard disk being easily damaged or dropped. Some styles of U disk have encryption and other functions, making users more personalized. The USB flash drive is compact and easy to carry. The life of the U disk depends mainly on the life of the flash memory. The memory chip can be erased at least 1,000,000 times.


    It is also important to pay attention to careful maintenance during use. For example, never pull out the flash drive when the indicator light of the flash drive is flashing fast, because the USB flash drive is reading or writing data, and pulling out in the middle may cause hardware and data damage. In addition, do not close the relevant program immediately after the backup document is completed, because the indicator light on the USB flash drive is still flashing at that time, indicating that the program has not completely ended. At this time, the USB flash drive is pulled out, which easily affects the backup. Therefore, after the file is backed up to the flash disk, it should take some time to close the relevant program to prevent accidents; the same reason, when the system prompts "cannot stop", do not easily pull out the U disk, which will also cause data loss.


    The U disk, which was also a luxury item in the past few years, has now put down its value and is increasingly approaching the average consumer. Compared with the traditional three-inch disc, the U-disk is not only a big belly, but also can hold a variety of "body" huge photos, music, games, it is not vulnerable to external damage, and can better ensure data security. . It is also important to pay attention to careful maintenance during use. For example, never pull out the flash drive when the indicator light of the flash drive is flashing fast, because the USB flash drive is reading or writing data, and pulling out in the middle may cause hardware and data damage. In addition, do not close the relevant program immediately after the backup document is completed, because the indicator light on the USB flash drive is still flashing at that time, indicating that the program has not completely ended. At this time, the USB flash drive is pulled out, which easily affects the backup. Therefore, after the file is backed up to the flash drive, it should take some time to close the relevant program to prevent accidents. Similarly, when the system prompts “cannot stop”, do not pull out the USB flash drive easily, or the data will be lost.


    In addition, pay attention to the U disk in a dry environment, do not let the U disk interface exposed to the air for a long time, otherwise it will easily cause surface metal oxidation, reducing interface sensitivity.


    At the same time, be careful not to reverse insert to avoid burning.


    Do not plug the U disk that has not been used for a long time on the USB interface. Otherwise, it will easily cause the interface to age. On the other hand, it is also a loss to the U disk.
