I forgot about the ExpressCard being one lane of PCIe; what a waste. ExpressCard seems extra silly since it was often available on machines with USB 2.0, which was faster than PCIe 1 1x. No wonder it never took off for most.
- rasz 7y agoSingle lane of pcie 2.0 is over 14x faster than usb 2.0 (realistic 35 MB/s in optimal circumstances), pcie 1.0 is still >7x faster.
- yttriumtyclief 7y agoThis, the 480Mbit/s rating for USB 2.0 is bits, not bytes. USB2 theoretically caps out at 80MB/s (realistically much much lower) whereas even PCI-E 1.1 can hit 250MB/s (2.5Gbit/s before 8b/10b encoding overhead) in a single lane.
