Actual storage capacity of storage products such as USB drives, memory cards, hard drives, and discs may be slightly less than the labeled capacity due to manufacturer algorithms differing from those of the operating system. It is a common industry practice to have a slight discrepancy between actual and labeled capacities. For example, for discs: 700M-700M; 4.7G~4.38G; 8.5G~7.92G; 25G-23.29G; 50G~46.59G. The speed indicated on discs is the theoretical recording speed, with the range 1-16X meaning the maximum speed can reach 16X, not the standard speed. Factors affecting recording speed include laser head aging, computer settings, compatibility between the recorder and disc, and recorder not supporting high speeds. It is recommended not to record at the highest speed to maintain recording quality and success rate.
