+ 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).
