PCIe 6.0 promises super-fast speeds in 2021

USB and to a lesser Thunderbolt often get the lion's share of attention when it comes to data transfer speeds between devices. But when it comes to ferrying data between a computer's internal components, PCI Express, more popular in marketing by its abbreviated "PCIe" name, is the name of the game. In order to catch up with growing demands for faster transfer of large files, the PCI Special Interest Group (PCI-SIG) announced that, in two years, the spec will double its data rate up to 64 GT/s.
