decent SD cards can do 200 or 300 MB/s of reads now

  Those speeds are... complicated. UHS-I cards easily go up to 100MB/s. This is the baseline for a modern SD card. After that you can add more pins for UHS-II. This is used in a bunch of devices and goes up to 300MB/s, but you can't assume anything will have it. And UHS-III was dead on arrival. Alternatively you can add a different set of more pins for SD Express. It can do gigabytes per second and is probably the future. It's backwards compatible with UHS-I, but not II or III. And also SanDisk made their own spec for overclocking UHS-I which some things support. It can do about 200MB/s. The steam deck supports none of those upgrade paths. You get about 100MB/s.

  Not in the Steam Deck, it maxes out at 104Mb/s. Considering the insane tempuratures the cards reach, and that it destroys brand new SD cards, I don't want them going any faster until it works safely.

    The Steam Deck only supports up to UHS-I. There are UHS-II and UHS-III cards out there that support higher bandwidth.
