Notes

  • Kernel commit 94fe2580a2f3bb055fdca86a2adf156d01f15764 enabled erase/discard/trim support for all MMC hosts (default in 5.8).
  • TRIM can slow down some drives, especially if it's unqueueable on those devices.
  • F2FS is specifically designed to handle the characteristics of storage devices with flash memory.
