USB 2 has very poor latency for this use case and the sd connector lacks the pins for newer sd cards. A usb 3 UHS III reader would be able to talk to the card

USB 2 has very poor latency for this use case and the sd connector lacks the pins for newer sd cards.
A usb 3 UHS III reader would be able to talk to the card at full speed, then it's a matter of convincing the OS to trim it and buffer as if it's an internal hdd. Kinda expensive and pointless to go to that effort to get 2x hdd performance when there are NVME enclosures for cheaper SSDs that have 100x the IOPs though.
