  15           Many flash memories support erasing small (4096 B) sectors. Depending
  16           on the usage this feature may provide performance gain in comparison
  17           to erasing whole blocks (32/64 KiB).
  18           Changing a small part of the flash's contents is usually faster with
  19           small sectors. On the other hand erasing should be faster when using
  20           64 KiB block instead of 16 × 4 KiB sectors.
  21
  22           Please note that some tools/drivers/filesystems may not work with
  23           4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).
