The maximum length for SuperSpeed USB 3.0 is indeed 3 meters. This specification is important because it allows for high-speed data transfer while maintaining signal integrity over a reasonable distance. USB 3.0 is designed to support data transfer rates up to 5 Gbps, and exceeding the 3-meter distance can result in signal degradation, which can lead to reduced performance and reliability.

Shorter cable lengths, such as those listed in the other choices, can offer improved signal quality, but the 3-meter limit is crucial for ensuring that devices can communicate effectively without significant loss of data quality or transfer speed. Thus, the 3-meter maximum provides a practical balance between length and performance, making it the optimal choice for many applications involving USB 3.0 connections.
