+// By default SPIFFS in some cases relies on the property of NOR flash that bits
+// cannot be set from 0 to 1 by writing and that controllers will ignore such
+// bit changes. This results in fewer reads as SPIFFS can in some cases perform
+// blind writes, with all bits set to 1 and only those it needs reset set to 0.
+// Most of the chips and controllers allow this behavior, so the default is to
+// use this technique. If your controller is one of the rare ones that don't,
+// turn this option on and SPIFFS will perform a read-modify-write instead.
