USB 3.0 hasn’t even reached mass popularity (or adoption) yet and already someone, somewhere is trying to steal it’s spotlight. 4.8Gbps may seem fast, and in truth, it really is. But there’s always something bigger and better, right? Right. NEC has gone on the record books claiming that the USB 3.0 spec can actually go faster.
How’s 16Gb/s sound? Such speeds will no doubt be part of future USB spec ratifications in USB 4.0 and beyond. Let’s not get ahead of ourselves though. The biggest problem with super speedy USB over longer distances is the signal interference and breakdown of the transmission. Countering such a problem involves sending a simple signal back down the line to confirm that it was sent correctly. But as you increase the transfer speeds, the speed of that “confirmation signal” has to increase as well. And such things can only go so fast.
NEC’s solution: delay the feedback/confirmation signal and dramatically increase the transfer speeds. In theory it’s simple, effective, and makes sense. The real world as we know it however, rarely works that way. Looks like USB 3.0 just became a little less cool huh? Ready for 16Gb/s USB?
