Logical sector size for physical sector size of 4096

  • 772

With many new hard drive disks the physical sector size is 4096. Would it be possible to make the system use a logical sector size of the same size, rather than the default logical sector size of 512?

How would you configure that?

    There is a difference between block size and cluster-size but there is no such thing as logical sector size in ext4.

    Probably you already have an IO block of 4096: try doing a stat .bash_logout in your home directory.

      File: ‘.bash_logout’
  Size: 220         Blocks: 8          IO Block: 4096   regular file

    For more info: man mkfs.ext4

    And finally: Stop worrying! ext4 uses heuristics to format your drive as efficiently as possible. ;-)
