code: @Override
  	public void noCheckWrite(long[] array) {
  	    LongBuffer lb = buf.asLongBuffer();
  	    lb.put(array);
  	    buf.position(buf.position() + S_LONG * array.length);
  	}
docs: The no-check methods are thought to be faster, because they don't need range checking.
  Furthermore, they ensure that a page can be filled to the last byte. without a new page
  being allocated.
