The Speed of SS USB

The “superspeed” performance of SS USB is entirely due to technological improvements. SS USB utilizes the bidirectional data transfer mode. In other words, data only needs to flow in one direction, which simplifies the time consumption caused by waiting.

In addition, compared with USB 2.0, SS USB provides much more sufficient bandwidth for various devices and applications. With the advent of high-definition video, digital cameras up to 10 million pixels, large-capacity mobile phones and portable media players, higher bandwidth and transmission speed offered by SS USB become a must.

For example, a flash drive with SS USB can transfer 1GB of data to a host in 15 seconds, while USB 2.0 takes 43 seconds.

Note: The theoretical maximum transmission rate of SS USB is 5.0Gbps (that is, 640MB/S), while the actual transmission rate is approximately 3.2Gbps (that is, 320MB/S).
