Data Anti-theft and Accurate Playback Retrieval:
Due to the minimum size of data block and higher I/O efficiency, UBS is able to retrieve recording data which contains even less than 1 second video. Thus playback retrieval can narrow down to time scale less than 1 second, which provides accuracy in finding exact playback data required.
In common file recording system, if there is a sudden power shutdown when the recording is not packed into one complete file, the data will be totally lost from Flash. Which may contain a few seconds of video. As for UBS technology, because all the video data is mapped and written into hard disk in time, a sudden power shutdown will not affect the recording.
