When writing data to a file using a FileOutputStream At what point is the data actually written to the file?
Write Performance It is faster to write an array of bytes to a Java FileOutputStream than writing one byte at a time. The speedup can be quite significant – up to 10 x higher or more. Therefore it is recommended to use the write(byte[]) methods whenever possible.
