Lenovo DVD+R Discs, 16x Speed, 4.7GB Capacity, Archive Series, 50 Pieces in A Barrel, Blank Optical Discs

The actual 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. The discrepancy in capacity is a common industry standard. For example, in the case of discs, 4.7GB is equivalent to 4.38GB. The speed indicated on discs represents theoretical recording speed, and factors such as laser head aging, computer settings, compatibility between the recorder and disc, and lack of high-speed support in the recorder can affect actual recording speed. It is recommended not to record at the maximum speed to maintain recording quality and success rate.
