What is the reason that u disk runs slowly?

Sometimes we use U disk when the speed is too slow, if the exclusion of infected computer viruses and U disk itself quality problems, may be because the use of U disk does not open the system "open after write cache" this function. The following is the specific way to write caching after opening:

Right-click "My Computer" and select "properties → performance → file system → removable disk". Before you enable the write-Behind Cache dialog box, click WinXP to open My Computer, right-click the removable disk, select Properties → hardware, and then select the disk drive where the flash memory resides Properties → policies, select the dialog box to optimize for performance ..., and click OK.

In the same way, it is also very important to pay attention to careful maintenance in use at ordinary times. For example, never in the U-disk lights flashing fast when pulling out a U disk, because then U disk is reading or writing data, halfway out may cause hardware, data damage. In addition, do not close the relevant program immediately after the backup document, because the flash drive on the light is still flashing, indicating that the program is not completely finished, then pull out the U disk, it is easy to affect the backup. So the file back to the U disk, you should have some time to close the relevant procedures to prevent accidents; the same reason, in the system prompts "can not stop" when you do not easily pull out the U disk, this will result in data loss.

In addition, note that the U disk in the dry environment, do not let the U disk interface for a long time exposure to the air, it is easy to cause surface metal oxidation, reduce interface sensitivity. At the same time, do not have a long time to not use the U disk has been inserted in the USB interface, or on the one hand will lead to aging interface, on the other hand is also a loss.
