What is the quickest way of writing large amounts of data to disk? For example, if using the character device driver to write directly to a disk, is filling a track quicker than filling the same sector on each platter (ie the same column of sectors in a cylinger)? If filling a track is quicker, is a certain pattern preferable over another: skip: 1, 6, 2, 7, 3, 8, 4, 9, 5 sequential: 1, 2, 3, 4, 5, 6, 7, 8, 9 Or perhaps could another method be devised using somekind of clever storing algorithm...
