IIUC, CFExpress is just a PCIe interface in a different form factor, so the adapter in the post should basically just be a pass-through. Conversely, a USB-C adapter would require some level of protocol adaptation/electronics/etc.

USB-C connectors can carry Thunderbolt which is essentially external PCI-Express, so the adapter might have to be very minimal if you’re fine with it only being compatible with Thunderbolt-capable devices.

  A Thunderbolt flash drive in the form factor of a USB-C YubiKey 5C Nano [0] would be the ultimate solution for me. I trust that some day we'll get there if it's not superseded by some other standard by then. [0] https://www.yubico.com/us/product/yubikey-5c-nano/ https://www.yubico.com/us/product/yubikey-5c-nano/

    Is there a USB-C flash drive smaller than the 2022 Samsung USB 3.2 Gen1, https://www.samsung.com/us/business/computing/memory-storage/usb-flash-drives/usb-type-c-256gb-muf-256da-am/ https://www.samsung.com/us/business/computing/memory-storage...? For USB-A there is Sandisk Cruzer Fit similar to Yubikey Nano, but most USB-C flash drives are larger.

Yep. We considered building an M.2 2230 NVMe USB-C adapter, but it was more efficient to just use a USB-C NAND Flash controller that interfaces the same types of flash that NVMe SSDs do. One less layer of translation.

  Who's we? :) And what are the controllers called? Plenty of USB-C SSDs on the market are actually M.2 in a trenchcoat, e.g. the nice looking black and orange SanDisk: https://www.reddit.com/r/hardware/comments/9631os/sandisk_extreme_usb_31_ssd_tear_down/ https://www.reddit.com/r/hardware/comments/9631os/sandisk_ex...
