MNDA CD-R Blank Discs/recordable Discs, Jiangnan Water Town Series, 52x Speed, 700MB Capacity, 50 Pieces in Plastic Packaging

The actual usable capacity of storage products such as USB drives, memory cards, hard drives, and optical discs is typically less than the nominal capacity due to differences in manufacturer and operating system calculation standards.

This discrepancy is an industry standard and results in normal variance between labeled and actual usable capacity.

For example, a disc labeled as 4.7GB corresponds to approximately 4.38GB in computer system units.

The labeled recording speed is theoretical; for example, 1-16X means the maximum speed can reach 16X but does not guarantee constant speed at 16X. Speeds within the range (e.g., 1-2X, 1-4X, 1-8X, 1-52X) are all considered normal.

Factors affecting actual recording speed include laser head aging, computer settings, compatibility between recorder and disc, and recorder support for high speeds.

It is recommended not to use the highest speed for recording to ensure better quality and success rate.
