Vehicle DVR currently uses three storage modes: hard disk, U disk and SD card. Compared with U disk, the reliability of U disk is higher.
1. U-disk has no mechanical moving parts and low power consumption. It can be used on buses with severe bumps and poor power supply environment.
2. It is convenient to transcribe data. By inserting the U disk directly into the computer USB interface, the video can be replayed and saved without the need for hard disk connectors, USB adapters and so on. The operation is simpler.
3. The interface design of U-disk is more reliable than SD card because it is suitable for repeated plug-in and pull-out.
