This code has been adapted from BlueSCSI/BlueSCSI-v2#191 It uses an updated SDFat library to report a warning if the SD card's speed class is below 10. Co-authored-by: androda <3105206+androda@users.noreply.github.com>
With some more changes the SdFat library, now all targets have a speed class warning. Including No Arduino builds and builds that use SPI instead of SDIO.
The sds struct need to be aligned on a 32 bit boundary because it is filled via the DMA. If not, depending on how the memory map gets compiled it can cause the board to freeze.
