sentences:  However some software provides virtual CD/DVD drives which can produce new disk images; this type of virtual drive goes by a variety of names, including "virtual burner".Using disk images in a virtual drive allows users to shift data between technologies, for example from CD optical drive to hard disk drive.This may provide advantages such as speed and noise (hard disk drives are typically four or five times faster than optical drives, are quieter, suffer from less wear and tear, and in the case of solid-state drives, are immune to some physical trauma).
