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