At least for components like LogStorage in TinyOS-2.x, the data are written synchronously to flash. However, due to metadata issues, the last bit of flash written may not be accessible until you issue sync(), which ensures that the metadata necessary to access that last bit has been written. Note that 'bit' is not a literal bit, but some implementation dependent amount of data. Also note that issuing sync() may waste some flash. TEP 103, available form www.tinyos.net, describes the state of flash components in TinyOS-2.x pretty well; you should check it out.
