upstart writes in with an IRC submission for carny:

SD cards hop on the PCIe 4.0 bus to hit 4GB/s with version 8.0 of storage spec:

As outlined in a whitepaper [PDF] this month, the new spec will let existing SD Express and microSD Express cards employ PCIe 4.0 and NVMe to deliver a top speed data transfer speed of [3938 MB/s].

While the new spec is backwards-compatible, the latest top speed will only come with a card reader capable of connecting to the extra row of pins present on SD Express cards that support dual PCIe lanes.

[...] The good news is that SD Express and microSD Express cards can still get to 1970 MB/s on a device with a single PCIe 4.x lane under version 8 of the specification, and SD Express can get there with a pair of 3.x lanes. Which is rather faster than many SSDs and, as SD Express can climb to 128TB on a single card, a rather tasty storage option.

Also at The Verge, PetaPixel, and Yahoo! Finance.
