USB4 Clocking in at 40 Gbps

This “PC World” and other USB4 related stories are emphasizing the upcoming USB4 spec compatibility, so to speak, with Thunderbolt. While this is understandable, given that its port can be used by devices of both protocols, I cannot get enough of the bandwidth that USB4 promises! 40 Gbps is outrageously fast!

Although this is actually equivalent to the bandwidth or data transfer rate of Thunderbolt, remember that this is USB we are referring to! USB 2.0 speeds clocked in at around 480 Mbps. So … this is incredible progress. Unfortunately, the USB4 spec will not be officially in effect at stores until about 2020.
