Even though USB 3.0’s top speed is 4.8Gbps, we may not have to wait for USB 4.0 to reach even faster speed. According to Jeff Ravencraft – the chairman of USB Promoter Group – was discussing the possibility of increasing the speed of USB 3.0 without a complete rewrite such as USB 3.0 itself and 2.0. He claimed USB 3.0 was designed with transmission protocol to support speed of up to 25Gbps.
While he couldn’t specify when USB 3.0 (aka. SuperSpeed USB) will hit that mark, he did imply the current 4.8Gbps speed will be enough for the next few years (likely within 5). It’s very possible that SSDs will be mainstream by then, and they are going to easily saturate USB 3.0 bandwidth. Perhaps we might only see a minor upgrade to USB 3.1 yet speed boost could be 3 to 4 times faster than what USB 3.0 currently offers.
