It may seem hard to believe, but storage makers are already approaching the limits of the PCI Express 4.0 bus in a typical NVMe drive, with the latest controller designs pushing transfer speeds in the neighborhood of 7 gigabytes per second (GB/s). That being the case, Silicon Motion is already at work developing controllers that leverage the PCI Express 5.0 bus. Before we get to that, let's go over the bandwidth limits of each PCI Express specification to date, starting with PCI Express 1.0... PCIe 1.0: 2.5GT/s transfer rate, 250MB/s per lane bandwidth, 4.0GB/s x16 bandwidth PCIe 2.0: 5.0GT/s transfer rate, 500MB/s per lane bandwidth, 8.0GB/s x16 bandwidth PCIe 3.0: 8.0GT/s transfer rate, 1GB/s...
