The data storage time of the USB flash drive is related to the quality of the USB flash drive itself and the type of memory chip and daily use, generally 5-10 years. The number of erasable times of the USB disk is the normal life of the USB disk, and the general USB disk can be erased (note that it is not read and write) more than 5000 times. The quality of the U disk itself is no problem and there is no unexpected situation (strong vibration, water, etc.), the data inside can be stored for a long time. Note: The U disk is placed in a dry environment, do not let the U disk port interface exposed to the air for a long time, otherwise it is easy to cause surface metal oxidation, reduce the sensitivity of the interface.
Do not use the U disk for a long time has been plugged into the USB interface, otherwise on the one hand, it is easy to cause the interface aging, on the other hand, the U disk is also a loss.
