Comment on Linux update adds support for 128 terabyte SD cards— SDUC and UHS-II SD cards are now supported

  I’m not sure I’m following, what was the technological leap here? I know that the SD, SDHC, SDXC, etc. are marketing terms and their limitations are based on other factors, much of the previous ones are file system related.

  • SD - FAT16 Volume size limit, Practical limit 2GB, Max limit 4GB
  • SDHC - FAT32 limit Set at 32GB by Microsoft (fake limit)
  • SDXC - 2TB limit, Maximum partition size for MBR partition Scheme.

  I assume that it’s a similar story here but it might not be, if so I’m curious as to what changed.

    The I/O commands are different as well, the hardware has to support SDUC.
