SD 8.0 Card Connector

SD Express 8.0 represents the bleeding edge of high-speed non-volatile memory. Like CFexpress cards and the M.2 NVMe SSDs you see in many computers these days, SD Express 8.0 is a form of PCIe NVMe storage. In this case, the new spec is taking advantage of the PCIe 4.0 standard to reach speeds of almost 2GB/s per lane, with the fastest cards giving you two lanes to work with.
