Before moving on with the review of the Pioneer drives, we should analyse the basic differences between these two similar but not identical models. As we mentioned before, both drives have the same specifications but there is something that separates them. The loading mechanism (i.e. the way the media is inserted in the drive) of the K14L drive has the classic tray loading mechanism where the media is inserted onto an ejecting tray. The K04L on the other hand, uses the caddy mechanism where the media is inserted into the drive through a vertical slot, without the use of a loading tray.
